Affected Rule

pyt_test

Is this a regression?

No

Description

py_test gives err if the value of the name arg is not the same as the test python script name. eg:

py_test(
    name = "test_script",
    srcs = ["test_module1/test_script1.py"],
    deps = [
        "//src:module1",
    ],
   # main = "test_module1/test_script1.py",
)

py_test(
    name = "test_script2",
    srcs = ["test_module2/test_script2.py"],
    deps = [
        "//src:module2",
    ],
  #  main = "test_module2/test_script2.py",
)

If I change the value of the name args something different from test_Script1.py or test_Script2.py, I got this err:

 bazel test //tests:all

However, if I give the main attribute with test script path then it works perfectly:
 main = "test_module1/test_script1.py",





## 🌍  Your Environment


issue coming on both windows and mac with latest bazel version

This works as intended, because each test rule needs a script to execute and it defaults to a script with the same name from the srcs list and you can override it with the main attribute.
