WebDriver: How to deal with parallel test execution using the same browser (Firefox)?

1. i need to execute many tests and many instances of the same browser however im having problems with cookies because the browsers are sharing the cookies used.

2. Possible to resolve the issue using browser / firefox profiles?

thanks for your help

Answer 1

1. Delete cookies before every test using driver().manage().deleteAllCookies()
2. Create new webdriver instance for every test
3. When running in parallel use forks instead of threads, refer to this article for more details: http://maven.apache.org/surefire/maven-surefire-plugin/examples/fork-options-and-parallel-execution.html - also you're able to use forks in testNG
