Earlier inwards previous post, We accept learnt how to develop examine execution priority of WebDriver test cases If you lot accept multiple tests In same class. TestNG has i to a greater extent than real useful characteristic of setting examine execution dependency. Dependency agency If one @Test method fails or skipped from execution thence It's dependent @Test method must non live on executed.
Supposing you lot are testing online electronic mail application using selenium WebDriver in addition to you lot accept ii @Test methods In your cast : 1) For LogIn in addition to 2) For Check Mail. Now due to the unopen to reasons (Invalid credentials), LogIn @Test method fails. In this instance you lot non bespeak to execute Check Mail @Test method because how tin dismiss you lot banking concern stand upwardly for emails without LogIn In electronic mail application? In this case, You tin dismiss use dependsOnMethods with @Test notation of Check Mail method to skip Its execution.
I accept created uncomplicated illustration every bit bellow to demonstrate how It works.
Example :
package TestNG_Advanced; import org.testng.Assert; import org.testng.annotations.Test; world cast setPriority { //This Is Independent method thence It volition live on executed. @Test(priority=1) world void Login() { System.out.println("LogIn Test code."); //Bellow laissez passer on assertion volition neglect to neglect Login() method Intentionally. Assert.assertTrue(5>6, "Condition Is False."); } //This method Is depends on Login method. //This method's execution volition live on skipped from execution because Login() method volition fail. @Test(priority=2, dependsOnMethods={"Login"}) world void checkMail() { System.out.println("checkMail Test code."); } //This method Is depends on Login in addition to checkMail methods. //This method's execution volition live on skipped from execution because Login() method volition fail. @Test(priority=3,dependsOnMethods={"Login","checkMail"}) world void LogOut() { System.out.println("LogOut Test code."); } //This Is Independent method thence It volition live on executed. @Test(priority=4) world void checkLogInValidations() { System.out.println("checkLogInValidations Test code."); } }TestNg upshot volition looks similar bellow.
- LogIn() method Is failed because nosotros accept written incorrect status In assertion.
- checkMail() and LogOut() methods are skipped from execution because they are depends on LogIn() method which Is failed.
- checkLogInValidations() method volition live on executed because It Is Independent.
So this way, We tin dismiss develop dependency on @Test methods to skip Its execution If It's depends on method fails.
