I’m having issues when using expect.objectContaining() because the result diff is unreadable and I always tried to use toMatchObject() to avoid that issue.

I have a product code that injects javascript into document head. I want to write unit test for it. The problem is that jest fails with timeout error. I understand it’s the resolve method of Promise that needs to be called, but I am unable to figure out how will I do it with jest. I tried to create document from JSDOM, but in that approach as well, the promise will not be resolved.

In the Jest documentation, the default value for the testMatch configuration option is [ “/tests//.[jt]s?(x)”, “**/?(.)+(spec|test).[jt]s?(x)” ]. My question is, since we want to match file extensions like .js, .jsx, .ts, and .tsx, why is it not .[jt]sx??

I have a test function that uses a file in the following path in my nestjs application:
/Users/username/Documents/projectname/src/assets/responses/message.hbs
This path is provided by a file service and is build from the application path, that is:
'application path'+'assets/responses/message.hbs'

I use jest for tests on my project and i had recieved an error after i started my test.
It has started after i had added dataformat to my project

I use jest testing framework. And I use git worktree and I have a different branch as a directory. So now I have two __tests__ directories:

I want to exclude a specific folder to be scanned for tests.

I have the following js file:

beforeEach(() => { mockAxiosFunc.post.mockImplementation((addres) => { if(addres == XXXX) { return Promise.resolve({res: XXXX}) } return Promise.reject(XXXX) }) }) I checked the relevant code and there does not seem to be a trigger either jestjs New contributor cindy is a new contributor to this site.
