如何更改 Jasmine-node 异步规范的超时

Why not by spying on setTimeout()?

Something like:

var spy = spyOn(window, 'setTimeout').andCallFake(function (func, timeout) {
expect(timeout).toEqual(2500);
func();
});


setTimeOut(function () { ... }, 2500);
expect(spy).toHaveBeenCalled();

Sent pull request for this feature (https://github.com/mhevery/jasmine-node/pull/142)

it("cannot change timeout", function(done) {


request("http://localhost:3000/hello", function(error, response, body){


expect(body).toEqual("hello world");


done();
});


}, 5000); // set timeout to 5 seconds

To set the global Jasmine-Node timeout, do this:

jasmine.getEnv().defaultTimeoutInterval = timeoutYouWouldPrefer;// e.g. 15000 milliseconds

Credit to developer Gabe Hicks for figuring out the .getEnv() part via debugging in spite of misinformation in the README doc which claims it's done by setting jasmine.DEFAULT_TIMEOUT_INTERVAL.

If you want to set a custom timeout just for one it(), you could try passing the timeout (milliseconds) as a third argument (after the string statement and the function). There's an example of that being done here, but I'm not sure what would happen if the custom timeout was longer than Jasmine's default. I expect it would fail.

Looks like you can now add it as the last argument for the it function:

describe('my test', function(){
it('works', function(done){
somethingAsync().then(done);
}, 10000); // changes to 10 seconds
});

You can (now) set it directly in the spec, as per Jasmine docs.

describe("long asynchronous specs", function() {


var originalTimeout;


beforeEach(function() {
originalTimeout = jasmine.DEFAULT_TIMEOUT_INTERVAL;
jasmine.DEFAULT_TIMEOUT_INTERVAL = 10000;
});


it("takes a long time", function(done) {
setTimeout(function() {
done();
}, 9000);
});


afterEach(function() {
jasmine.DEFAULT_TIMEOUT_INTERVAL = originalTimeout;
});
});

Change j$.DEFAULT_TIMEOUT_INTERVAL to 10000 in following file: npm\node_modules\jasmine-core\lib\jasmine-core

Adding: jasmine.DEFAULT_TIMEOUT_INTERVAL = yourTime; on a helper file worked for me.

In Angular, put this outside your describe block:

jasmine.DEFAULT_TIMEOUT_INTERVAL = 10000;

This applies to all the tests in the .spec.ts file

Put it after describe statement:

describe("A saves to DB", function() {
jasmine.DEFAULT_TIMEOUT_INTERVAL = 10000;

In my case I had multiple tests cases and while I was using the aforementioned solution with was using the:

    beforeEach(function() {
originalTimeout = jasmine.DEFAULT_TIMEOUT_INTERVAL;
jasmine.DEFAULT_TIMEOUT_INTERVAL = 10000;
});

the DEFAULT_TIMEOUT_INTERVAL was not updated at the first test case, so I had to add this:

  beforeAll(() => {
jasmine.DEFAULT_TIMEOUT_INTERVAL = 10000;
})

to my code to successfully run all the tests.

To do this globally for all of your tests (in the case of e2e or integration testing) you can use a helper.

A helper file when configured correctly should get loaded before the tests are executed and allow you to change the DEFAULT_TIMEOUT_INTERVAL globally:

spec/support/jasmine.json

{
...
"helpers": [
"/path/to/helpers/**/*.ts"
]
}

helpers/timeout.ts

jasmine.DEFAULT_TIMEOUT_INTERVAL = 300000;
