We can execute tests using XML suite file as shown in below example.Syntax of Suite file
- suite tag contains one or more test tag. Each test tag can contains one or more tests to be executed.
- A test tag can contain tags like classes, groups etc. We can also pass the attribute preserver-order which is used to specify if the tests should be executed in given order.
- In test tag, preserve-order attribute is used to run the tests in the order as given in XML file
- In test tag, group-by-instances attribute is used to group tests by test class instances
Running tests from specific classes
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Softpost Suite">
<test name="softpostTests" preserve-order="true" >
<classes>
<class name="org.softpost.AppTest">
<methods>
<include name="test1"/>
<exclude name="test2"/>
</methods>
</class>
<class name="org.softpost.TimeoutTests" />
</classes>
</test>
</suite>
Running Tests from package
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Softpost Suite">
<test name="softpostTests" preserve-order="true" >
<packages>
<package name="org.softpost"/>
</packages>
</test>
</suite>
Running tests from Specific Groups
Notice that when running the tests from a group, you need to also specify the packages or classes containing tests from those group.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Softpost Suite">
<test name="softpostTests" preserve-order="true" >
<groups>
<define name="desktop_browsers">
<include name="chrome"/>
<include name="ie"/>
</define>
<define name="mobile_browsers">
<include name="android"/>
<include name="ios"/>
</define>
<run>
<include name="desktop_browsers"/>
<exclude name="mobile_browsers"/>
</run>
</groups>
<packages>
<package name="org.softpost"/>
</packages>
</test>
</suite>
