Get the current test/spec name in Jest

Question

Is there a way to get the current spec name from within the running test?

Basically I want to save a file, eg. using a function saveFile(), with the nam

Answer 1

I found that the only possible way was through the use of expect(), which contains the spec name in its this. doing something like

expect.extend({
  async toSaveFile(data) {
    fs.writeFileSync(`${this.currentTestName}.txt`, data)
    return { pass: true };
  },
});

allows to then do

expect().toSaveFile('contents of the file');

it's definitely a hack, but it's the only way I could find to get a reference to the spec name. there is also this.testPath that indicates the test file
