What is TestNG dependsOnMethods?

What is TestNG dependsOnMethods?

dependsOnMethods ensures that a test method runs only after the specified method runs successfully.

If the dependent method fails or is skipped, the depending method will also be skipped.

✅ Basic Example

import org.testng.annotations.Test;

public class LoginTest {

 @Test
 public void openBrowser() {
 System.out.println("Browser opened");
 }

 @Test(dependsOnMethods = "openBrowser")
 public void login() {
 System.out.println("User logged in");
 }

 @Test(dependsOnMethods = "login")
 public void verifyHomePage() {
 System.out.println("Home page verified");
 }
}
 

🔎 Execution Order

1. openBrowser()
2. login() (runs only if openBrowser() passes)
3. verifyHomePage() (runs only if login() passes)

❌ What Happens If a Method Fails?

If openBrowser() fails:

• login() → SKIPPED
• verifyHomePage() → SKIPPED

🔹 Multiple Dependencies Example

@Test
public void startServer() {
 System.out.println("Server started");
}

@Test
public void connectDatabase() {
 System.out.println("Database connected");
}

@Test(dependsOnMethods = {"startServer", "connectDatabase"})
public void runTests() {
 System.out.println("Tests running...");
}
 

Here, runTests() runs only if both methods pass.

🔹 Using alwaysRun = true

@Test(dependsOnMethods = "openBrowser", alwaysRun = true)
public void login() {
 System.out.println("Login attempted even if browser failed");
}
