Running test cases with Regex

In this topic, we will use the regular expressions to include/exclude test methods from the test suite execution.

Now we will consider an example to understand how to use Regex for running test cases in TestNG.

Step 1: Let's create a java project.

Step 2: Till now, we have created the java file. If we want to include only those test cases which are starting with a keyword "Mobile". To achieve this, we need to configure testing.xml file and after configuration, it would look like:

Note: The pattern /sequence .*/ searches the string which is starting with the sequence keyword including space character. The '*' asterisk represents the remaining characters.

In the above testing.xml configuration file, we include all the test cases represented by the starting keyword 'Mobile' with a pattern Mobile.* in <include> tag.

Step 3: Run the testng.xml file. Right click on the testng.xml file and move the cursor down, click on the 1 TestNG Suite.
