Shashavali, as
groovyguy pointed you can save the project required run type / mode.
Of course, you can quickly change that from project xml file as well( in case, modifying thru file, have backup of it), look for value of "runType".
Note the below:
1. The setting is available at project level and test suite level. i.e., the suites, test cases can be run in parallell mode respectively.
2. You should be careful if you are setting test suite level and you have hundreds of test cases ( meaning more number of cases). Because, it creates as many threads as the number of test cases and your local machine where tests are executed and the application should be capable of handling those many threads.
