The script appears to be wrong , as far as i know pytest.main can be used if you want your pytest should be run by python interpreter. You need have have your test under a directory. For example your pytest file is called test_sample which has following content ===================================pytests/test_sample===============================

    import pytest
    def func(x): return x + 1
    def test_answer(): assert func(3) == 5

================================================================================== Then you can have the following code in python file which runs your test_sample

   pytest.main(args=['-s', os.path.abspath('pytests')])

This should solve your problem

If you dont want python to run your pytests you can configure pyscripter runner to be run by pytests via tools-->configure tools and then add the pytests command line argument. you can then run you pytest from tools. By default pyscripter uses python interpreter as runner
