An-dy1 / testng-practice

Building my first test suite with TestNG framework.

Notes

• When Rahul runs his @Test, it shows PASSED: [method name], but I don't get that in mine
• TestNG is incorporated in IntelliJ and doesn't require download - just have to include in pom.xml if Maven project
• One class can incorporate several test classes using @Test annotation

Required to run tests with TestNG?

• Must have @Test annotation
• Followed by method(s)
• Can have several @Test annotations in one class

TestNG.xml file

• Triggers run
• Whereas Eclipse can auto-generate a TestNG.xml file, IntelliJ doesn't have that feature, so I added a template in my IntelliJ setup
• Read about it in the documentation: https://testng.org/doc/documentation-main.html#testng-xml
• XML hierarcy:
  • Test Suite > Test Folder (shell/module) > Test Cases
  • is self-closing
• To run all test cases in a module/package: run testng.xml file

Prioritizing test cases

• TestNgPriority1 and 2 classes
• Could potentially just comment out the test cases in your testng.xml file

Run a test case with everything but some number of specific methods:

• Add body to class tag to exclude a certain method:

<class name="com.testng.tutorial.TestNgPriority2">
    <methods>
        <exclude name="ApiLoginBreck" />
    </methods>
</class>

• Or include only a certain method:

<class name="com.testng.tutorial.TestNGBasics">
    <methods>
        <include name="Demo" />
    </methods>
</class>

Executing test cases at package level with regex

• What if you want to exclue (or include) all test methods that include "Mobile" in its name?

<class name="com.testng.tutorial.TestNgPriority2">
    <methods>
        <exclude name="Api.*" />
    </methods>
</class>

• What is regex?
  • A regular expression, regex or regexp is a sequence of characters that define a search pattern. Usually such patterns are used by string searching algorithms for "find" or "find and replace" operations on strings, or for input validation.
• Run by package (in my case, com.testng.tutorial)
  • Remove all classes, replace with:

  <package name="com.testng.tutorial" />

  • This will run every test in the package
  • Useful for running a regression test
