 Then, we store the name of the test class and test function, initialise the asyncio event loop, and the appropriate test object:

 Now, add an ‘if’ statement that ensures that the setup code runs before the test function is called. In this example, we will have a test class called ‘Test_Copy’, and the test function will be called ‘test_copy’:
 ~~~
-	if class_name == "Test_Copy":

 Time to write the setup code – Under ```if test_name == "test_copy":```, let’s store the test file name as a variable, use the genScenarios method to copy that file to the endpoints, and store the outputs:

 Next, define the test class and within it, the test function.

 class Test_Copy:

 When parametrizing the test, we passed the arguments:
 ```metafunc.parametrize("cmdOut, destsums, destderrs", testCases, ids=outputs[‘IDs’])```
 
 Pass these same arguments to the test_copy function:
 ~~~
-	def test_copy(self, cmdOut, destsum, destderr):
+    def test_copy(self, cmdOut, destsum, destderr):
         (returncode, stdout, stderr), srcsum = cmdOut
 ~~~
 We also unpacked the ```cmdOut``` argument to get the individual ```returncode, stdout, stderr``` and ```srcsum``` values for the scenario.
 
 Now we can add the assert statements. For the copy test to pass, the copy command’s returncode should == 0, and the srcsum and destsum should match:
 ~~~
-		assert returncode == 0, f"Upload Failed: {stdout}, {stderr}"
+        assert returncode == 0, f"Upload Failed: {stdout}, {stderr}"
