Spy assertion seem incorrect when used inside a setInterval
Using jest 26.6.3, I cannot make the second test here working fine. If I add logs, I can see the callback being called….
How to test that a method was called exactly once with specific arguments?
I’m aware of toHaveBeenCalledWith
and toHaveBeenNthCalledWith
, but I want a call with certain parameter exactly once (or, more generally, N times). How do I check that? In other words, I care about number of calls and about arguments passed, but not about order of calls.
Frontends are already using React- script , do i have to configure additionally jest to run the tests as a QA? [closed]

global.window is undefined after upgrading Jest
We had a dependabot pull which is upgrading jest, jest-cli and braces from the following versions:
jest.mock with requireActual but specific implementation for test case
Currently I have 2 test like this, the first one is ok, the second needs to overwrite some implementation:
Jest mock $ as a function and object
I need to write test cases for a function which has $ as argument. But the $ argument is being used as a function and an object
Run two specific tests using testNamePattern in jest
I’m trying to run a set of tests using jest
NodeJS zlib onError causing jest tests to fail even if it is handled
I have a function that uses a stream pipeline consisting of a fs.createReadStream
a zlib.createGunzip
and an XML parser as per: await pipeline(readStream, gunzipStream, xmlParser)
Jest CLI: How can I get very short output, ~1 character per test file?
The default jest output prints one file per line, and the cli options don’t appear to have options for it. I can use --silent
to prevent console.log
from within tests and --noStackTrace
to hide stack trace when a test fails, but nothing to hide or customize the bulk of the output.
