If you are asking if there is a specific litmus test for being appointed a federal judge, the answer is no. Any competent citizen may be appointed and confirmed. "Competent" and "citizen" are the only two actual requirements. Having a law degree is not required.
The term "litmus test" is generally a pejorative way of describing some idea that a senator (or perhaps the president, or even a lobbying group) believes a candidate must possess in order to be qualified for judgeship. In reality, litmus tests are simply opinions that people hold dear to them; the only reason they are relevant is that since federal judges must be confirmed by the Senate, senators may apply a litmus test when making up their mind whether to approve or disapprove the candidate.
Additional Information:
While there are no constitutional requirements and no specific litmus tests for federal judges and justices; the President usually considers the recommendation and evaluation of the American Bar Association's Standing Committee on the Federal Judiciary, which suggests minimum criteria for nomination to the Article III (constitutional) courts:

test for bases.
Litmus is a colored powder, obtained from certain lichens, that changes to red in an acid solution, and to blue in an alkaline solution. Litmus is a mixture of various closely related heterocyclic organic compounds. It is used to make litmus paper , which can be used to determine whether a solution is basic or acidic by dipping a strip of the paper into the solution and seeing how the paper changes color.
When ammonia gas is produced at the bottom of the test tube and comes in contact with the litmus paper at the mouth of the test tube, it reacts with the water on the litmus paper to form ammonium hydroxide. This reaction changes the color of the litmus paper from red to blue, indicating the presence of ammonia gas. The ammonia gas diffuses up the test tube to reach the litmus paper due to differences in concentration.
