问题 I have in packadge.json "scripts": { "test": "cross-env NODE_ENV=test jest" }, I want to test all files match pattern front/**/*.test.js but if "scripts": { "test": "cross-env NODE_ENV=test jest \"front/**/*.test.js\"" }, I've got an error Invalid testPattern front/**/*.test.js supplied. Running all tests instead. So, how could I pass file names pattern to jest? Thanks. 回答1: According to the documentation you are supposed to use a regex for your pattern. So in your case you probably would

问题 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 name of the file being the spec name. Without having to manually retype the name of the test. 回答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

问题 I am using Jest to perform unit tests on a Node.js app, where the code source is written in TypeScript and then compiled into JavaScript. In one of the classes that I wish to test, an external module is imported and a method from this module is used. I want to mock the calls to this method, in order to test only my code. However, when I run the test, I get the following error: TypeError: Cannot redefine property: methodName The problem is that this method has the following Object Properties:
