Running a specific test class

mvn test -Dtest=Test/LoginTests.java

Running a specific test case in a class

mvn test -Dtest=Test/LoginTests.java#loginTestWithInvalidCredentials

Running a single xml

mvn clean test -DsuiteXmlFile=testng.xml

mvn clean verify -Drunner=testng.xml

Running all the xml files mentioned in the pom.xml:

mvn clean test -DsuiteXmlFile

All of the tests are independent from each other, UNLESS we create dependency.

The plugin maven-surefire-plugin is used to configure and execute the tests and generate test reports.

• The @DataProvider annotation is used to provide test data to the tests.
• It allows you to separate the test data from the test logic.
• With @DataProvider, your test data can be reusable.
• Basically we have a method annotated with @DataProvider that returns a two dimensional array object containing the data.
• We specify a name for our data provider, and we it to link the dataprovider to the test.

Example of usage:

@DataProvider(name = "loginData")
public Object[][] provideLoginData() {
    return new Object[][] {
        { "user1", "password1" },
        { "user2", "password2" },
        { "user3", "password3" }
    };
}

@Test(dataProvider = "loginData")
public void testLogin(String username, String password) {
    // ...
}

In our framework, we have also a BaseDataProvider class where we store the test data. This class is extended by the BaseTest class.
