GitHub - Immortale-dev/QTest: QTest is a C++ Behavior Driven Development testing framework

What the Freak ?

QTest is a C++ Behavior Driven Development testing framework. There is a lot of good test frameworks like google-test or catch2, and if you are looking for the great, popular test frameworks with huge community, you should probably try them first, but if you are looking for the lightweight test framework that looks so familiar and simple, or you would like to contribute and modify some test framework for your specific project or environment, and you don't know what to start from, or you don't want to use huge test frameworks for your project, you might found QTest as a good thing for your needs. Just take a look for the syntax and some examples, and you may fell in love with it :)

Build

You can use QTest for both Windows and Linux platforms. C++11 or later version of compiler required. You can find make file in the root of repository used to build the test program. Also, there is test.cpp file that shows some useful examples of how to use this test framework. If you want quickly build and run the example tests, you can run test.bat or ./test.sh depends on platform you are using (Windows or Linux respectively). This script will build the test.cpp program, run it, and clear working directory after test run is completed.

Dist

Additionally we've generated single .hpp file you can use to include full testing framework functionality. You can find this file placed to /dist folder. It is lightweight - less than 25kb totally.

Docs

Usage

QTest is a behaviour driven C++ test framework. To start working with it, you need to include qtest.hpp file to your test project. You can download single qtest.hpp file from /dist folder of this repository, or use it separated.

After .hpp file included, you can start writing tests using several predefined macros explained in the Macros section of documentation.

We will move through all of them below.

Example:

#include "qtest.hpp"

SCENARIO_START

DESCRIBE("[Test]", {
	int a,b,c;
	BEFORE_EACH({
		a = 1;
		b = 2;
		c = 3;
	});
	DESCRIBE("Ariphmetic Operations", {
		IT("sum of `a` and `b` should be equal to `c`", {
			EXPECT(a+b).toBe(c);
		});
	});
});

SCENARIO_END

int main(){return 0;}

Notice, we don't need to put our tests to main() or any else function. Because of that, it is allowed to split your tests to different files, and include them separately to your general file after including the qtest.hpp.

Notice, you must put every your DESCRIBE macro between one one SCENARIO_START / SCENARIO_END. It is not required to have exactly one scenario, you could have multiple, and you could put multiple scenarios to each your test file.

Example:

// Include framework
#include "qtest.hpp"

SCENARIO_START
// Include testing files
#include "testAriphmethics.cpp"
#include "testMyProgramCode.cpp"
#include "testAnotherOneThing.cpp"
SCENARIO_END

int main(){return 0;}

Syntax

It is important to follow the syntax rules of building test cases:

All your EXPECT macros must be called directly from IT macro wrapper.
And all IT macros must be called directly from DESCRIBE macro wrapper.
All BEFORE_ALL, BEFORE_EACH, AFTER_ALL and AFTER_EACH macros must be called directly from DESCRIBE macro wrapper.
DESCRIBE macros must be called from another DESCRIBE macro wrappers, or as independent from "test tree" call.
All DESCRIBE macros should be placed between SCENARIO_START and SCENARIO_END macroses

Not following those rules may cause undefined behavior.

Correct examples:

SCENARIO_START
...
DESCRIBE("...", {
	int a=3,b,c;
	BEFORE_EACH({ ... });
	AFTER_EACH({ ... });
	IT("...", {
		int a,x=10,z=5;
		EXPECT(5+5).toBe(10);
		EXPECT(11/2).toBe(5);
	});
	IT("...", {
		EXPECT(...).[...](...);
	});
	IT("...", {
		EXPECT(...).[...](...);
	});
	
	DESCRIBE("...", {
		double a, anotherDouble = 13.5, etc;
		IT("...", {
			EXPECT(5+5).toBe(10);
		});
		BEFORE_ALL({ ... });
		AFTER_ALL({ ... });
	});
});
DESCRIBE("...", {
	IT("...", {
		EXPECT(...).[...](...);
	});
});
...
SCENARIO_END

Incorrect examples:

...
DESCRIBE("...", {
	// Incorrect. You MUST use `EXPECT` directly from `IT`
	EXPECT(5+5).toBe(10);

	BEFORE_EACH({
		// Incorrect. You MUST use `IT` directly from `DESCRIBE`
		IT("...", {
			EXPECT(...).[...](...);
		})
	});

	IT("...", {
		// Incorrect. You MUST use `BEFORE_ALL` directly from `DESCRIBE`
		BEFORE_ALL({ ... });
	});

	if(stars_lined_up){
		// Incorrect. You MUST use `IT` directly from `DESCRIBE` code scope (not from `if`, `while` or any another)
		IT("...", {
			EXPECT(...).[...](...);
		});
	}
});
...

Code scope

You can use all global variables inside any of predefined macros, also, all variables that were defined in one of the DESCRIBE macro code scope will be available as a reference in all "child" macro calls. Formally, you can treat the

DESCRIBE("...", { /* More code here */ });

as actually call of lambda function with reference variables rule

[&](){ /* More code here */ });

And you can rely on such lambda functionality behavior.

Example:

...
DESCRIBE("Some test", {
	int a = 10;
	IT("`a` should be equals to 10", {
		EXPECT(a).toBe(10); // Works as expected
	});
	DESCRIBE("Inner describe", {
		IT("`a` should still be equals to 10", {
			EXPECT(a).toBe(10); // Works as expected
		});
	});
	DESCRIBE("One more inner describe", {
		int a = 5;
		BEFORE_ALL({ /* `a` is accesible and equals to 5 */ });
		IT("`a` should be equals to 5", {
			EXPECT(a).toBe(5); // As expected
		});
	});
});
...

Macros

There are 2 system macroses you should use to define "borders" for all your test cases:

SCENARIO_START
SCENARIO_END

To build your test cases you are allowed to use the following predefined c++ macro functions:

DESCRIBE
BEFORE_ALL
AFTER_ALL
BEFORE_EACH
AFTER_EACH
IT
EXPECT

Few more macros that allow us to debug code while testing it:

DESCRIBE_SKIP
DESCRIBE_ONLY
IT_SKIP
IT_ONLY

Two more macros to work with test cases:

TEST_SUCCEED
TEST_FAILED

And one macro for providing additional information to the test case result:

INFO_PRINT

Lets move through all of them

SCENARIO_START

System macro you should use to define beginning of your test cases

Example:

SCENARIO_START
...
DESCRIBE("...", {
...

SCENARIO_END

System macro you should use to define ending of your test cases

Example:

SCENARIO_START
...
DESCRIBE("Test", {
...
});
DESCRIBE("Another Test", {
...
});
...
SCENARIO_END

DESCRIBE (string description, {})

DESCRIBE macro used to group some test cases, enclose the scope, split up the test cases, and provide the useful description for the group of tests, or preparation part. The description is going to be generated using current and all parent to current DESCRIBE's. It is receive 2 parameters: first one is the string description - which is the simple text description that will be used to generate the group of test overall description, and the second one is the "code scope" to be ran (see examples to get the better understanding).

Example: Consider we have the next structure of our test cases:

...
DESCRIBE("Test numbers", {
	DESCRIBE("With floating point", {
		DESCRIBE("Generated by arithmetic operations", {
			...
		});
		...
	});
	...
});
...

Notice, we didn't put SCENARIO macroses in the examples, but they are required in real test cases

And consider we have the IT macro (which is the real test definer) placed to each of the "describe", the result would be the following:

Test numbers
- Test case 1
- Test case 2
- ...
Test numbers With floating point
- Test case 1
- Test case 2
- ...
Test numbers With floating point Generated by arithmetic operations
- Test case 1
- Test case 2
- ...

But if one of DESCRIBE blocks does not contain direct IT calls, then this group of tests will not be showed (as it is not contains any test cases, so it does not make sense to show it).

DESCRIBE_SKIP (string description, {})

DESCRIBE_SKIP macro has the same syntax, call rules and used for the same purposes as DESCRIBE, but instead of running the tests, it is actually skip all the test cases with its preparations (BEFORE_... and AFTER_...) of current DESCRIBE_SKIP and all of it children ones.

This macro also used for the debugging purposes, when you want to disable tests to be running, for a while (or intentionally disable some of the test cases).

Skipped tests will anyway be showed in the test results, but they will be marked as "(skipped)" and indicated with different color.

DESCRIBE_ONLY (string description, {})

DESCRIBE_ONLY macro has the same syntax, call rules and used for the same purposes as DESCRIBE, but it is disabling all tests to be called outside of the DESCRIBE_ONLY (or IT_ONLY) blocks. (All of it children tests will be called as well).

This macro also used for the debugging purposes, when you want to focus on one or few important DESCRIBE's while building the test cases. But unlike the DESCRIBE_SKIP, tests that was "filtered" by DESCRIBE_ONLY rule will not be showed in the test results.

Important: this macro will work as expected only if additionally TEST_ONLY_RULE variable is defined before the #include "qtest.hpp". Otherwise it will work as a simple DESCRIBE rule.

Example:

...
#define TEST_ONLY_RULE
#include "qtest.hpp"

DESCRIBE("...", {
	// Will not be called
	IT("...", { ... });
	// Will not be called as well
	BEFORE_EACH({ ... });
});
DESCRIBE_ONLY("...", {
	// Will be called as wrapped to `DESCRIBE_ONLY`
	IT("...", { ... });
	// Will be called as well
	BEFORE_EACH({ ... });
});
DESCRIBE("...", {
	// Will be called as IT called with ONLY rule as well
	IT_ONLY("...", { ... });
	// Will be called as well, as this code preparation block relates to the test above.
	BEFORE_EACH({ ... });
});

BEFORE_ALL ({})

This macro requires only the code scope to be passed as a first parameter. The code inside the brackets will be called only once, before the first test from the DESCRIBE where this BEFORE_ALL placed is executed. Usually this rule is used to initialize the variables needed for the test cases.

Example:

...
DESCRIBE("Test step array values", {
	int* arr;
	BEFORE_ALL({
		arr = new int[10];
		arr[0] = 2;
		for(int i=1;i<10;i++)
			arr[i] = arr[i-1]*2;
	});
	IT("the 5th item from `arr` should be equal to 32", {
		EXPECT(arr[4]).toBe(32);
	});
	IT("the 10th item from `arr` should be equal to 1024", {
		EXPECT(arr[9]).toBe(1024);
	});
});

AFTER_ALL ({})

This macro requires only the code scope to be passed as the first parameter. The code inside the brackets will be called only once, after the final test case of the DESCRIBE where this AFTER_ALL placed is executed. Usually this rule is used to release the memory assumed by the test cases.

Example:

DESCRIBE("Test step array values", {
	int* arr;
	BEFORE_ALL({
		arr = new int[10];
		arr[0] = 2;
		for(int i=1;i<10;i++)
			arr[i] = arr[i-1]*2;
	});
	AFTER_ALL({
		delete[] arr;
	});
	IT("...", { ... });
	IT("...", { ... });
});

BEFORE_EACH ({})

This macro requires only the code scope to be passed as the first parameter. The code inside the brackets will be called before every test case of the DESCRIBE where this BEFORE_EACH placed to, and all of this children DESCRIBE's test cases. Usually this rule used to make some variable preparations that needs to be similar before each test case.

Example:

DESCRIBE("Test std::set", {
	std::set<int> s;
	BEFORE_EACH({
		s.clear();
		s.insert(10);
		s.insert(15);
		s.insert(5);
	});
	IT("first element of `s` should be 5", {
		EXPECT(*s.begin()).toBe(5);
	});
	IT("last element of `s` should be 15", {
		EXPECT( *(--s.end()) ).toBe(15);
	});
	DESCRIBE("After removing first element from s", {
		BEFORE_EACH({
			s.erase(s.begin());
		});
		IT("first element of `s` should be 5", {
			EXPECT(*s.begin()).toBe(10);
		});
		IT("last element of `s` should be 15", {
			EXPECT( *(--s.end()) ).toBe(15);
		});
	});
});

AFTER_EACH ({})

This macro requires only the code scope to be passed as the first parameter. The code inside the brackets will be called after every test case of the DESCRIBE where this AFTER_EACH placed to, and all of this children DESCRIBE's test cases. Usually this rule used to make some variable release memory after each test case, or clear mutable changes.

Example:

DESCRIBE("Test std::set", {
	std::set<int> s;
	BEFORE_EACH({
		s.insert(10);
		s.insert(15);
		s.insert(5);
	});
	AFTER_EACH({
		s.clear();
	});
	IT("first element of `s` should be 5", { ... });
	IT("last element of `s` should be 15", { ... });
	DESCRIBE("After removing first element from s", { ... });
});

IT (string description, {})

This macro is used to define the actual test case. First parameter requires string description that represents the description of the test case that will be showed in test results, and the second parameter is a code scope of current test. You can define as many additional variables as you need inside the test code scope to execute the actual test.

Example:

...
DESCRIBE("Some very important test", {
	IT("the size of vector should be one more than the size of hash table", {
		vector<int> v{1,1,2,3,5,8,13};
		unordered_set<int> s;
		for(auto &it : v){
			s.insert(it);
		}
		EXPECT(v.size()).toBe(s.size() + 1);
	});
});
...

IT_SKIP (string description, {})

IT_SKIP macro has the same syntax, call rules and used for the same purposes as IT, but instead of running the test, it is actually skip it.

This macro usually used for the debugging purposes, when you want to disable tests to be running for a while (or intentionally disable some of the test cases).

Skipped tests will anyway be showed in the test results, but they will be marked as "(skipped)" and indicated with different color.

IT_ONLY (string description, {})

IT_ONLY macro has the same syntax, call rules and used for the same purposes as IT, but it is disabling all another tests to be called that are not marked as _ONLY.

This macro also used for the debugging purposes, when you want to focus on the one or few important test cases, but unlike the IT_SKIP, tests that were "filtered" by IT_ONLY rule will not be showed in the test results.

Important: this macro will work as expected only if additionally TEST_ONLY_RULE variable is defined before the #include "qtest.hpp". Otherwise it will work as a simple IT rule.

EXPECT (T value)

This macro used to resolve the test case. It is required one parameter to be passed. You can send any value type you want, this macro will return QTestExpect class instance, which has different methods to proceed with. You can find all available methods in QTestExpect class section.

You can use as many EXPECT calls as you need for every separate test case.

Exapmle:

...
IT("the `a` variable should be between `10` and `15`", {
	EXPECT(a).toBeLessThan(15);
	EXPECT(a).toBeGreaterThan(10);
});
...

TEST_SUCCEED ()

This macro requires no parameters to be passed, and used only inside the IT macro code scope and will succeed the test case it is used for. This macro equivalent to EXPECT(1).toBe(1) .

Example:

...
IT("Should succeed", {
	TEST_SUCCEED();
});
...

TEST_FAILED ()

This macro requires no parameters to be passed, and used only inside the IT macro code scope and will fail the test case it is used for. This macro equivalent to EXPECT(1).toBe(0) .

Example:

...
IT("Should fail", {
	TEST_FAILED();
});
...

INFO_PRINT (string str)

This macro accepts one optional parameter to be passed string str and used to provide additional information to the test case. Used only inside the IT macro code scope and will print the text you pass after the test case result. It also returns a std::basic_ostream object, so you can use << operator to continue putting some more info to the info log.

Example:

...
IT("Additional info", {
	if(stars_lined_up){
		TEST_SUCCEED();
		INFO_PRINT("Stars Lined Up") << " don't forget to take a photo!";
	}
});
...

QTestExpect (T actual)

This class used to make some "predictions" about the value you passed to EXPECT macro. It is requires one parameter to be passed (any type allowed). The class contains bunch of methods you can use to assert your actual value with some expected one. There is a list of all methods allowed:

toBe (to_be)
toBeCloseTo (to_be_close_to)
toBeGreaterThan (to_be_greater_than)
toBeGreaterThanOrEqual (to_be_greater_than_or_equal)
toBeLessThan (to_be_less_than)
toBeLessThanOrEqual (to_be_less_than_or_equal)
toBeNull (to_be_null)
toBeNullPtr (to_be_null_ptr)
toBeIteratableEqual (to_be_iteratable_equal)
toThrowError (to_throw_error)
toReturnTrue (to_return_true)

And one method NOT() that will return another QTestExpect instance, but the result of all methods described above will be reversed.

Lets move through.

toBe (T compare)

Method used to compare expected value with the actual value you have. It is requires one parameter to be passed. Notice, type of compare should be the same as type of actual value, that was passed to EXPECT macro. Example:

...
IT("Varialbes should be equal", {
	long a = 10;
	int exp = 10;
	EXPECT(a).toBe((long)exp);
});

IT("Vector size should be 10", {
	EXPECT((int)(vector<int>{1,2,3,4,5,6,7,8,9,10}).size()).to_be(10);
});

// Will throw an error
IT("Classes to be equal", {
	struct A{ ... };
	struct B{ ... };
	EXPECT(A()).toBe(B());
});
...

Note: There is also to_be alias for this method allowed.

toBeCloseTo (double compare, double precision)

Method used to compare actual value to be within a specified precision of the expected value. It is requires 2 double parameters to be passed: the compare and precision. This method will succeed the test if actual value lies within the [compare - precision , compare + precision] range.

Example:

...
IT("a should be close to 15 with precision of 0.5", {
	auto a = 15.5;
	EXPECT(a).toBeCloseTo(15, 0.5);
});
...

Note: There is also to_be_close_to alias for this method allowed.

toBeGreaterThan (T compare)

Method will succeed test if the actual value is greater than the expected value. Requires one parameter to be passed with the same type as actual value you put to EXPECT macro.

Example:

...
EXPECT(15).toBeGreaterThan(10);
...

Note: There is also to_be_greater_than alias for this method allowed.

toBeGreaterThanOrEqual (T compare)

Method will succeed test if the actual value is greater than or equal to the expected value. Requires one parameter to be passed with the same type as actual value you put to EXPECT macro.

Example:

...
EXPECT(15).toBeGreaterThanOrEqual(15);
...

Note: There is also to_be_greater_than_or_equal alias for this method allowed.

toBeLessThan (T compare)

Method will succeed test if the actual value is less than the expected value. Requires one parameter to be passed with the same type as actual value you put to EXPECT macro.

Example:

...
EXPECT(15).toBeLessThan(20);
...

Note: There is also to_be_less_than alias for this method allowed.

toBeLessThanOrEqual (T compare)

Method will succeed test if the actual value is less than or equal to the expected value. Requires one parameter to be passed with the same type as actual value you put to EXPECT macro.

Example:

...
EXPECT(15).toBeLessThanOrEqual(15);
...

Note: There is also to_be_less_than_or_equal alias for this method allowed.

toBeNull ()

Method will succeed test of the actual value is equal to NULL. No parameters required.

Example:

...
int* a = NULL;
EXPECT(a).toBeNull();
...

Note: There is also to_be_null alias for this method allowed.

toBeNullPtr ()

Method will succeed test of the actual value is equal to nullptr. No parameters required.

Example:

...
int* a = nullptr;
EXPECT(a).toBeNullPtr();
...

Note: There is also to_be_null_ptr alias for this method allowed.

toBeIterableEqual (CT compare)

Method used to compare your iterable object with the list of items (or another iterable object). It is requires one parameter to be passed to compare with.

Important: Iterable objects - the objects that have predefined methods such as begin and end that returns Iterator object

Example:

...
auto vec = vector<int>{5,6,7,8,9};

IT("vec should toBeIterableEqual to {5,6,7,8,9}", {
	EXPECT(vec).toBeIterableEqual({5,6,7,8,9});
});

IT("vec should toBeIterableEqual to list<int>{5,6,7,8,9}", {
	list<int> comp;
	for(int i=5;i<10;i++)
		comp.push_back(i);
	
	EXPECT(vec).toBeIterableEqual(comp);
});
...

Note: There is also to_be_iterable_equal alias for this method allowed.

toThrowError ()

This method requires the function to be passed to EXPECT macro. When called, it will succeed the test case, if the function passed to EXPECT is going to throw an error.

Example:

EXPECT([](){ throw "error here"; }).toThrowError();

Note: There is also to_throw_error alias for this method allowed.

toReturnTrue ()

This method requires the function to be passed to EXPECT macro. When called, it will succeed the test case, if the function passed to EXPECT is going to return true.

Example:

EXPECT([]() -> bool { return 1; }).toReturnTrue();

Note: There is also to_return_true alias for this method allowed.

NOT ()

This method does not requires any parameters to be passed, and will return another QTestExpect class instance, but with reversed results of methods. See examples to get better understanding.

Example:

EXPECT(42).NOT().toBe(72) 

EXPECT(15.5).NOT().toBeCloseTo(15,0.49);

EXPECT([](){
	int foo = 5;
	int bar = foo%2;
	foo = bar+foo;
	// party hard...
}).NOT().toThrowError();

// All EXPECT's succeed

Tips

Garbage test result

For Linux users: If after executing test, you can see some garbage instead of actual test results, most probably your console does not support colors. If you anyway want to continue using this console to view the test results, you can try the following option for turning off the colored test results. To do that, all you need is to define TEST_RESULTS_NO_COLOR variable before the include test framework .hpp file.

Example:

...
#define TEST_RESULTS_NO_COLOR
#include "qtest.hpp"

DESCRIBE("...", {
...

Cycles and conditions

You are not allowed to use cycles for tests definitions.

Example:

...
DESCRIBE("Test `calc` method", {
	vector<int> v{1, 5, 10, 1000, 42, 525, 1024, 0, -1, -999};
	int index = 0;

	AFTER_EACH({
		// Increment index
		index++;
	});

	for(int i=0;i<v.size();i++){
		IT("with "+to_string(v[i]), {
			EXPECT(yourTestObject.calc(v[index])).toBe(true);
		});
	}
});
...

It will not work as you MUST call IT directly from DESCRIBE macro block scope. Same with DESCRIBE macros.

But it is allowed to use cycles and conditions inside the IT macro.

Example:

...
IT("Bunch of checks", {
    for(int i=0;i<10;i++){
        EXPECT(i).toBeLessThan(10);
    }
});
...

Expect object aliases

Each of the QTestExpect class instance methods (except NOT) has aliases in snake case format (small characters delimited with underscore _ character).

Example:

...
EXPECT(1).to_be(1);
EXPECT(15.5).to_be_close_to(15,0.5);
EXPECT([](){...}).NOT().to_throw_error();
...

"ONLY" rule

If you are going to use DESCRIBE_ONLY or IT_ONLY macros, don't forget to put #define TEST_ONLY_RULE before the #include "qtest.hpp"

"SCENARIO" macroses

Due to recent changes in C++ (2 y.o. actually, lol) it is not permitted anymore to use default-capture lambda functions in non-local scope, so I had to define additional macroses to make everything works again. Now, you MUST put all your DESCIBE macros between SCENARIO_START and SCENARIO_END macroses.
