Launchers / Automated tests

Protractor Launcher (protractor.jar)

The Protractor launcher allows running tests using the Protractor utility against angular UI .
The launcher allows to:
  • Scan existing protractor *.js scripts files
  • Automatically create the corresponding test cases in XStudio
  • Manage this as a test, hence include it into a test campaign
  • Automatically start, run and kill the Selenium server with Chrome and Gecko drivers
  • Attached the log and resulting files to the test case results
  • Setting the right environment variables (JAVA_HOME and path) during execution
Please refer to Protractor's home page for understanding the adequate context to use Protractor.
Note: Protractor is a nodeJs module - hence you need to have nodeJs, npm and the Protractor module already installed for the test to run
Latest test with: Windows 10-17134, Protractor R.3.2, nodeJs 8.11.2, npm 5.6.0
This version of the launcher is initial (v1.0)

Configuration

The protractor.xml file is just a template and must NOT be edited.
It's used by the system to dynamically build the form that the user will be able to fill in from the GUI when creating a custom execution configuration.

Parameter Description
General
Test root path This sets the location where the Protractor *.js scripts reside.
This path MUST NOT include an ending slash.
Notes:
- not all *.js files are protractor test scripts in that destination but XStudio find them
- in this version of the launcher, we do not search for TypeScript files - you can adapt the launcher for it

Default value is: C:\MyProtractorTests
Java Home This sets the location where the java executables resides.
This path MUST NOT include an ending slash.

Default value is: C:\Program Files\java\jdk1.8.0.172
Protractor
Node.js install path This must indicate where nodeJs is installed
This path MUST NOT include an ending slash.

Default value is: C:\Program Files\nodejs
Npm install path This must indicate where npm is installed
This path MUST NOT include an ending slash.

Default value is: C:\Users\<testuser>\AppData\Roaming\npm
Chrome driver path This must indicate where Chrome web driver is installed
This path MUST NOT include an ending slash.

Default value is: C:\Users\<testuser>\AppData\Roaming\npm\node_modules\protractor\node_modules\webdriver-manager\selenium\chromedriver_2.40.exe
gecko (for Firefox) driver path This must indicate where gecko web driver is installed
This path MUST NOT include an ending slash.

Default value is: C:\Users\<testuser>\AppData\Roaming\npm\node_modules\protractor\node_modules\webdriver-manager\selenium\geckodriver-v0.21.0.exe
Selenium server path This must indicate where selenium server is installed
This path MUST NOT include an ending slash.

Default value is: C:\Users\<testuser>\AppData\Roaming\npm\node_modules\protractor\node_modules\webdriver-manager\selenium\selenium-server-standalone-3.12.0.jar
Selenium address This must indicate selenium server address

Default value is: localhost
Selenium port This must indicate selenium server port

Default value is: 4444
Selenium options This may indicate selenium server options

No default value

These values can be changed while creating the campaign session from XStudio.
Note about file path parameters:
Any parameter referring to a file or folder path (for instance Test root path) can be provided either using \ separator (if the tests are going to be executed on a Windows agent) or / separator (if the tests are going to be executed on a linux or MacOSX agent).

On windows, if you provide a path containing an OS-localizable folder such as C:\Program Files, always prefer the English version (i.e. NOT C:\Programmes if you're using a french-localized Windows) or the corresponding native environment variable (i.e. %PROGRAMFILES%).


Specific test attributes

It is possible to associate attributes to individual test.
This launcher does not make use of any test attributes.

Specific test case parameters (params)

It is possible to associate params to individual test case.
This launcher does not make use of any test case params.

Specific Envrionment variable set during test execution

<JAVA_HOME> is set to the Java Home
<path> is set to by adding Node.js install path to the current path

Process

1) The launcher first start the selenium server
<javaHome>/bin/java -Dwebdriver.chrome.driver=<chromeDriverPath> -Dwebdriver.gecko.driver=<geckoDriverPath>
-jar <seleniumServerPath> -port <seleniumPort> <seleniumOptions>

2)The launcher will constitute and run the interpreter with the following templates:
<npm install path>/protractor.bat or /protractor <test name>.js
--troubleshoot --logLevel DEBUG --resultJsonOutputFile jsonReport.json <test name>
--seleniumAddress http://<selenium address>:<selenium port>/wd/hub
3) The log file XStudioLogFile.txt and the jsonReport.json will be attached to the result
4) The launcher parses the specific XstudioLogFile.txt trace file and uses it to provide summarized information back to the testers
5) The launcher parses the specific jsonReport.json trace file and uses it to provide detailed information back to the testers
6) When the session ends, XStudio terminates the selenium server it started



Permissions

WARNING: if you're running your tests on Windows, it may be required to run the tests as administrator.
Having an account with Administrators permissions may even not be enough in some cases (especially if you're using Windows 10) and you may need to disable completely the UAC (User Access Control) on your computer.
To do so:
  • Press the Windows + R key combination
  • Type in regedit
  • Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
  • In the right-side pane, look for EnableLUA and set the value 0
  • Close the registry editor
  • Restart your computer

Debug

If your tests are not executed correctly or are reporting only failures, this is very likely because your configuration is incorrect or because you used a wrong naming convention for your tests and test cases.

The best way to quickly find out what's wrong is to look at the traces generated by XStudio (or XAgent).
The traces always include the detailed description of what the launcher performs (command line execution, script execution, API calling etc.) to run a test case. So, if you experiment some problems, the first thing to do is to activate the traces and look at what's happening when you run your tests.

Then, try to execute manually in a cmd box the exact same commands.
This will normally fail the same way.
At this point, you needs to figure out what has to be changed in these commands in order to have them run properly.

When you have something working, compare these commands to what's described in the Process chapter above. This will tell you exactly what you need to change.

Most of the time, this is related to:
  • some incorrect values in some parameters of your configuration,
  • the name of your tests,
  • the name of your test cases,
  • the canonical path of your tests
