Disadvantages of Parallel Testing
- Dependent module failed: Parallel testing allows independent modules to be run simultaneously, but often results in failure when modules are interdependent. This problem often arises during experiments that must be completed or sacrificed for independence, both of which require more time and effort.
- Debugging Complexity: Debugging parallel tests can be challenging due to concurrent execution, requiring more effort and time to pinpoint the root cause of failures or unexpected behavior.
- Program flow information: To create a balanced testing model, testers need to have a deep understanding of the flow. Even the slightest interdependence can destroy the entire successful experiment. Testers need to know which modules must run simultaneously and which modules must follow a pattern to ensure proper operation.
Parallel Testing with Selenium
In parallel testing, multiple tests can be run simultaneously in different execution modes, reducing execution time. This approach is particularly useful when running tests across multiple browsers or operating systems because it simplifies cross-browser testing. TestNG is often used with Selenium to provide seamless integration for execution.
