Test Data Preparation: Tips and Tricks
This document discusses best practices for test data preparation and management. It recommends generating test data before running tests to make tests independent. It also suggests using tools like OKHttp and Jackson to generate Java objects from JSON, send HTTP requests to log in instead of using the UI, and make each test independent by creating and cleaning test data. The document contrasts best practices like using page objects and avoiding Thread.sleep with bad practices like relying on XPath alone and not making tests independent.

A bug in another part of the application that is not exactly related to the test should not cause the test to fail. 2. Every test should be independent. The test outcome should not affected by another test in the suite. 3. Make a faster tests. As quicker test suite as much useful it is. 4. Every test should create and clean the data before and the after the test run. When we are talking about best practice in Selenium test, some of things often come up are:

BAD PRACTICE Gmail and Facbook Logins # WebDriver is not the ideal choice to automate login into websites like Gmail and Facebook, firstly because it is against their policy and secondly because it is slow and unreliable. The most appropriate choice would be to use the API that these websites provide.
