During interactive input, $TestFileName is "":

Wolfram Language code: $TestFileName

This test file prints $TestFileName when it is executed:

Wolfram Language code: file = FileNameJoin[{"ExampleData", "example.wlt"}]; FilePrint[file]

Execute the test file with TestReport:

Wolfram Language code: TestReport[FileNameJoin[{"ExampleData", "example.wlt"}]]

After the TestReport is complete, $TestFileName is "" again:

Wolfram Language code: $TestFileName

Open an example test notebook:

Wolfram Language code: file = FileNameJoin[{$InstallationDirectory, "Documentation", $Language, "System", "ExampleData", "ExampleTestFile.nb"}]; NotebookOpen[file]

Run the test report on the notebook:

Wolfram Language code: report = TestReport[file]

Get the test that tests $TestFileName:

Wolfram Language code: result = report["TestResults"][8]

Show the input, expected output and actual output for the test result:

Wolfram Language code: result[{"Input", "ExpectedOutput", "ActualOutput"}]//Dataset
