There are a few breaking changes in testx 1.0 compared to testx 0.x, but you should only need to change your configuration file and not your tests.
Reporting is no longer done by testx. Instead you should take care of it yourself. I've pulled out (and refactored a bit) the old reporting code into a separate package testx-jasmine-reporters.
This lead to the removal of the onPrepare and onComplete methods from the testx API. These methods were only adding the jasmine reporters and sending test results, respectively, so there is no need for them anymore. You should just remove the calls to them from your config file.
There is a slight change in the testx API.
Instead of
testx.addObjects(require './objects')
testx.addObjects 'objects/objects.csv'
testx.addKeywords(require './keywords')
testx.addKeywords(require 'testx-pdf-keywords')
testx.addFunctions(require './my-functions')
You will now do
testx.objects.add(require './objects')
testx.objects.add 'objects/objects.csv'
testx.keywords.add(require './keywords')
testx.keywords.add(require 'testx-pdf-keywords')
testx.functions.add(require './my-functions')
testx aims to make web application testing easier by using keyword driven testing.
testx uses MS Excel sheets as a platform for writing tests. Essentially you write your tests in MS Excel, utilizing the computational power of MS Excel. This will free you from having to implement all the things like generating random data, referring to values in other test steps. formatting dates, etc.
It is possible to use testx without MS Excel as well, but then it looses a lot of its usefulness. Of course if you don't want to shell out for MS Excel you can use any of the numerous copies like LibreOffice (OpenOffice) Calc, etc.
The tests consist of steps. Each step consists of a keyword and arguments.
The keyword is an action or a check (or both, can be anything really). The arguments consist of a name and a value. Both the name and the value can be literals, context references or object keys.
In MS Excel a test looks something like that (taken from the sample project):
url | ||
---|---|---|
go to | / | |
query-input | search-btn | |
set | new york | |
object | timeout | |
wait to appear | result-link | 4000 |
result-link | ||
check matches | New York |
You can think of the step as the action you want to perform using the provided arguments. In this context the keyword is the action.
The other key component at work here is the object map.
It is a dictionary of object keys - the stuff you put in your scripts to identify objects on the screen - and object locators.
Object locators are simple objects consisting of locator and value.
The locator can be any of the supported protractor element selector types, i.e. id, css, xpath, etc.
The value is the actual value of the selector - "element-id", ".hidden.button", "//input[@type='button']", etc.
Clients (test projects) use the addObjects method to add to the object map. For example (from the sample project conf.coffee)
testx = require 'testx'
onPrepare: ->
testx.objects.add require('./objects')
And in objects/index.coffee you'll have something like:
module.exports =
"query-input":
locator: "css"
value: "input[name='q']"
"search-btn":
locator: "css"
value: "button[name='btnG']"
"result-link":
locator: "css"
value: "li.g a"
Objects can also be read from CSV file. The file looks like this:
query-input,css,"input[name='q']"
search-btn,css,"button[name='btnG']"
result-link,css,"li.g a"
As of testx 0.7.0 objects ini the object map can be functions as well. This gives you the ability to parameterize object. This is easiest to explain with an example. Let's say you have this object definition:
module.exports =
"query-input": (attr, val) ->
locator: "css"
value: "input[#{attr}='#{val}']"
It can then be used to set an input element with arbitrary name like so (in your Excel sheet):
query-input('name','q') | |
---|---|
set | something |
In the example above "name" and "q" will be passed to the object function as the attr and val parameters and the return value of the function will be used to locate the element. In this example the resulting locator will be "input[name='q']". The only requirement is that the parameters you pass have to be put in quotes. If you want to have a quote (') as part of a parameter you need to escape it using back slash (\).
testx does its magic by augmenting the behaviour to the WebDriver elements. This is done by adding 3 functions to the WebDriver element:
- set - used to act on element uniformly. Mainly used by the set keyword.
- get - used to get the perceived value of the element. Mainly used by the check ... keywords.
- wait - used to wait for element state. Mainly used by the wait ... keywords.
As of testx 1.5.0 it is possible to add custom behaviour to objects in the object map. This is done by adding a behaviour attribute to the object definition. The behaviour is an object containing get, set and/or wait functions specific to this object. All these are optional - if omitted, the default behaviour will be used instead.
For example
"query-input":
locator: "css"
value: "input[name='q']"
behaviour:
set: (val) -> @sendKeys val
will override the set function for only that particular object. The this (@) object in the function is the instance of the WebDriver element. The get and wait functions for this object will take the defaults.
testx exposes the following interface:
-
runExcelSheet(filePath, sheetName, initialContext) - executes the test on the specified file path and Excel sheet passing initial test context. The parameters are: filePath - path to the Excel file, can be absolute or relative to the execution root; sheetName - the name of the Excel sheet containing the test script; initialContext - the initial context of the run. A JSON object. Attributes in the context must have scalar value. The context can be referenced with the {{contextVar}} syntax where contextVar is the key of the attribute. The initial context is optional, defaulting to an empty object.
-
keywords - the keywords extension end point; this object has two attributes and both are functions
- get() - returns the raw keywords object, usually not something you'll need;
- add(kwds) - makes the keywords passed as the only argument available to the current test run; adding a keyword with a name that already exists will overwrite the implementation of that keyword; the kwds argument can be
- object containing custom keywords
- parameterless function that returns a keywords object
-
objects - the objects extension end point; this object has two attributes and both are functions
-
get() - returns the raw objects object, usually not something you'll need;
-
add(objs) - adds the objects passed as the only argument to the object map; adding an object with a name that already exists will overwrite the definition of that object; the objs argument can be
- object containing custom your objects
- parameterless function that returns objects object :-)
- string that is assumed to be the path to a CSV file with your objects. The format of such a file is:
"object name", "locator type", "locator"
for example
"loginPass", "css", "input.password"
-
-
functions - the functions extension end point; this object has two attributes and both are functions
- get() - returns the raw functions object, usually not something you'll need;
- add(funcs) - makes the functions passed as the only argument available to the current test run context; adding a function with a name that already exists will overwrite the implementation of that function; the funcs argument can be
- object containing custom function
- parameterless function that returns a functions object
Functions are invoked using the context resolution syntax, i.e. {{functionName}} (in the Excel sheet) will invoke the function functionName. Currently only functions without parameters are supported.
testx will only work in protractor based projects. Supported protractor versions are 2.0.0 and up.
Create a protractor project. For a sample project clone https://github.com/testxio/testx-quickstart
Add this module to your project:
npm install testx --save
This is already done in the sample project so there you only need to:
npm install
From within the test project directory:
protractor conf.coffee --baseUrl=http://google.com
To be able to use testx you'll need to services external to it. One of them is essential - the xls(x) file to test converter, and the other one, the reporting service is optional and sending data to it is switched off by default.
All testx configuration lives in your protractor configuration file under params.testx, for example (in coffeescript):
params:
testx:
logScript: true
actionTimeout: 4000
The available configuration options are
- logScript - if true testx will log the test script (JSON) on the console before executing it; defaults to false.
- actionTimeout - the timeout in milliseconds before a get or set action will fail, for example because the target element is not visible; defaults to 5000.
testx comes with a simple set keywords that can be extended/overriden from the project. See the keywords.add method for details.
Predefined keywords are:
object key - the object key as specified in the object map. The keyword is applied to this object (DOM element). value of the object - this string value depends on the HTML type of the object. For example it will be the text of a label or the value attribute of an input element.
