如何更改 jasmine-node 异步规范的超时时间

Question

How can I get this test to pass without resorting to runs/waitsFor blocks?

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

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

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

         done();
     });
});

Answer 1

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;
    });
});

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
});

Answer 5

In Angular, put this outside your describe block:

jasmine.DEFAULT_TIMEOUT_INTERVAL = 10000;

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

Answer 6

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

Answer 7

Put it after describe statement:

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

Answer 8

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.

Answer 9

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;

Answer 10

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();

在以下文件中将 j$.DEFAULT_TIMEOUT_INTERVAL 更改为 10000：npm\\node_modules\\jasmine-core\\lib\\jasmine-core
