MethodScript Unit

Getting started

Four things need to be done to run tests

1. Init MSUnit
2. Register the folder (hereinafter referred to as the module), which will contain the tests
3. Write the tests
4. Enter command to run

Initializtion MSUnit

First include the main.ms script, then call the _init_msunit procedure

Like this:

// your includes
include('unit/main.ms')
// your includes

_init_msunit()

Attention: the tests will contain the environment that was at the time of the procedure call _init_msunit

Registration

Registration is done in one procedure:

_msunit_register_module(array(
  id: 'test',
  root: file_resolve('root')
))

• id - unique module name
• root - existing path to module

After recompile the following file structure is obtained:

/root
  /extension
    /main.ms
  /ms
  /resources
  /setting.yml

Tests

Test scripts must be in the ms folder and their names must end with '-test.ms'. The names of the tests themselves (procedures) must begin with _test.

Example

# ms/test-test.ms

proc _test_mytest(@test) {
    _print(@test)
    _assert_equals(1, 1)
}

@test is a unique name of test

Regarding the environment of test: all the procedures that were declared before the call of _init_msunit are visible, as for the global constants (import, export), they are not there - for each test they are their own and in start are empty, thanks to this you will not be able to influence the main one in any way server operation. You can enable the original globals by using the "--no-globals" flag.

In addition to the tests themselves, there are auxiliary procedures such as: _before_each, _after_all, e.t.c.

See in section auxiliary procedures

Command to run

To run the tests, just enter the msunit test command, where 'msunit' is name command and test is id module of tests.

Also, after the ID of the module, you can choose the group of tests you want to test, it can be either several scripts or one test! Groups can be selected and excluded by the "!" at the beginning of the group name, like !group. For a specific test, you need to specify the script group in which it is located and the script itself, separated by a colon: group:_test_mytest, they can also be excluded. For the most part, enabling exclusion of groups works like set mathematics where the element of set is the test.

After running the tests for the first time, something like this appeared in setting.yml:

test-test: [
  ]

Keys are the formatted names of scripts (replace / to . and remove .ms extension) and values is groups that indicate in command. Keys are also groups, only they include one test - themselves.

Examples:

test-test:
  - all
  - test
util-test:
  - all
  - util
logger-test:
  - all
  - util
  - log

• unit test - all tests
• unit test all - all tests
• unit test util - logger-test.ms, util-test.ms
• unit test util test - all tests
• unit test !test - logger-test.ms, util-test.ms
• unit test util !log - util-test.ms
• unit test util !all - no tests
• unit test !all test - test-test.ms
• unit test test:_test_mytest - test-test.ms : {_test_mytest}
• unit test test:_test_mytest, test:_test_secondtest - test-test.ms : {_test_mytest, _test_secondtest}
• unit test !test-test:_test_mytest - all tests except test-test.ms : {_test_mytest}
• unit test !all:_test_mytest - all tests except _test_mytest

Data files

In each test, you can create files that are deleted after the module test expires.They are located by default "root/data/@nameCurrentThread/".

You can save files by specifying the "--save-data" flag when running tests

---

Syntax command

unit <module> [--reinit] [--no-bar] [--save-data] [--no-globals] [groups...]

• module - id of module

• --reinit - module reinitialization (recompile tests, update settings)

• --no-bar - disable loading status bar

• --save-data - enable save data files

• --no-globals - cancels initialization of globals for each test

• groups - groups of tests

---

Auxiliary procedures

_before_all(testName)

Default pattern: _before_all.*

Runs one time before all tests

The return value is passed to the all tests as the second argument

_before_each(testName)

Default pattern: _before_each.*

Runs every time before tests

Accepts test name and the return value is passed to the test as the third argument

_after_all()

Default pattern: _after_all.*

Runs one time after all tests

_after_each(testName, returnTest)

Default pattern: _before_each.*

Runs every time after tests

Accepts test name and the value returned by the test

API

Registration

_msunit_register_module(array(
  id: test,
  root: file_resolve('root')
  [tests: string],
  [extension: string],
  [resources: string],
  [data: string],
  [setting_groups: string],
  [outs: array]
  [tests_setting: array]
))

• id - Unique identifier for pluggable tests
• root - Main path to all parts required for MSUnit to work
• tests - Local path to tests, by default "root/ms"
• extension - Local path to scripts, that runs before running tests, by default "root/extension"
• resources - Local path to resources, by default "root/resources"
• data - Local path to root data files for each test, by default "root/data"
• setting_groups - Local path to yml file map "test: [groups...]", by default "root/setting.yml"
• outs - array of loggers, taken from _msunit_get_outs by default
• tests_setting - see default value

Set options

To customize the framework for your machine, use the setup procedure:

void _msunit_set_options(array @options).

See the default value
