TestNG Errors

Error: TestNG ERROR Cannot find class in classpath


  1. Go to Eclipse> Project > Clean and then run the test cases again. It should work.
  2. And update the maven project (Project > Maven > Update Maven Project)

What it does in background is, that it will call mvn eclipse:clean in your project directory which will delete your .project and .classpath files and you can also do a mvn eclipse:eclipse – this regenerates your .project and .classpath files. Thus adding the desired class in the classpath.
