what is selenium grid

0 votes

So what I understand is, the purpose of the Selenium grid is NOT parallel execution. It is for remote execution. Parallel execution is achieved via TestNG. It is not possible to do parallel execution by only using Grid. Is this correct?

Selenium Grid is to execute the tests remotely on remote machines. The two main reasons to distribute your tests are:

  • Reduce execution time of your Test Suite.
  • To avoid memory (e.g. RAM) crunch on your localhost and you can find a couple of relevant discussions in:
  1. Limit chrome headless CPU and memory usage
  2. Many processes of Google Chrome
  3. Selenium using too much RAM with Firefox
  4. Is it possible to reduce memory RAM consumption when using Selenium Firefox
