== Why is this an issue?
|
|
|
|
Testing frameworks like Mocha and Jest provide a way to run a single test case for a file by appending `.only()` to the test function. This is convenient when debugging a specific use case. It makes, however, no sense to have it in production or development, and it was likely left by mistake after such a debugging session.
|
|
Therefore, it is strongly recommended not to commit usages of `.only()` to version control.

=== Noncompliant code example
|
|
|
|
[source,javascript]
|
|
----
|
|
describe("MyClass", function () {
|
|
it.only("should run correctly", function () {
|
|
/*...*/
|
|
});
|
|
});
