Difference between Parallelization vs Serialization
Parallelization aims to improve test performance by executing tests simultaneously, while serialization ensures that tests are executed one after another. The choice of this method depends on factors such as the needs of the test, available resources, and execution speed.
Parallelization | Serialization |
---|---|
In parallelization, multiple tests run simultaneously across different environments or configurations, reducing overall test execution time. | Serialization involves executing tests one after the other without overlapping with test execution. |
This approach uses a testing framework such as TestNG to distribute test data across multiple threads, processes, or machines. | Tests are executed sequentially, with each test starting only after the previous one has finished, preventing overlap between test executions. |
Parallelization can reduce execution times, especially for high-pressure tests or cross-browser tests. | Serialization is easier but potentially slower, especially for many tests or long tests. |
The use and control of parallelism will include monitoring parallel work and ensuring parallelism of tests. | Serialization is easier to implement and manage because tests run without having to deal with compatibility issues. |
Parallelization works well in situations where efficiency is required, such as managing multiple tests or running cross-browser tests. | For simpler tests or where specifying the application is important, serialization may be the preferred method. This option is important for the ease and speed of management, it speeds up the process for better management. |
Serialization refers to the process of executing operations one by one in a thread of execution. In short, tasks are performed sequentially and each task starts only after the completion of the previous task.
Parallelization means executing a series of tasks on multiple threads, where one task is assigned to one thread. So these tasks are done together. This approach makes better use of multiple CPU cores and can improve application performance and performance.
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.
