kubilaydogan / Test_Automation_with_TestNG

A framework template for demonstrating TestNg usage in Test Automation

Test Automation with TestNG

Features:

• POM pattern design
• Base Data Provider
• Custom Annotation Usage
• Various test runners (xml files)
• Logs
• Extent Report

Test Execution

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.

maven-surefire-plugin

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

Sample:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>${maven-surefire-plugin-version}</version>
       <configuration>
          <suiteXmlFiles>
              <suiteXmlFile>testng.xml</suiteXmlFile>          --> enter path
          </suiteXmlFiles>
          <parallel>methods</parallel>                  --> optional | for parallel execution
          <threadCount>10</threadCount>                 --> optional | for parallel execution
       </configuration>
</plugin>

<plugin>     
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.1.2</version>
    <configuration>
        <groups>P0,P1</groups>
        <excludedGroups>Flaky</excludedGroups>      --> optional
    </configuration>
</plugin>

@DataProvider annotation

• 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.
