How prevent error message when catching expected exception in test?
I have some code that I expect to throw an exception in a unit test (using Jest). I'm able to get the test to pass/fail as it should, but I get a nasty error message in my Jest watch. That message makes me think something bad happened, when in reality, it was the expected exception.
To explain why: the production code (not shown) makes a request using fetch. I have a previous test that mocks fetch out, and this test was to prove that I reset the state correctly.
Test code:
it('should not keep on mocking fetch', (done) => {
try {
wrapper.find('button#submit').simulate('click');
done.fail("Expected fetch to not be defined");
} catch (error) {
done();
}
});
How can I get rid of the error message for this test without affecting other tests?
I've tried reassigning global.console.error, which works, but that would be very bad if I forgot to reassign the real global.console.error back at the end of the test.
I've also tried using expect(...).toThrow(), but I still get the nasty error message.
