kandi X-RAY | Jasmine-Matchers Summary

Jasmine-Matchers is a JavaScript library typically used in Testing, Unit Testing, Jest applications. Jasmine-Matchers has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can install using 'npm i jasmine-expect' or download it from GitHub, npm.

A huge library of test matchers for a range of common use-cases, compatible with all versions of Jasmine and Jest. Custom Matchers make tests easier to read and produce relevant and useful messages when they fail. By avoiding vague messages such as "expected false to be true" in favour of useful cues such as "expected 3 to be even number" and avoiding implementation noise such as expect(cycleWheels % 2 === 0).toEqual(true) in favour of simply stating that you expect(cycleWheels).toBeEvenNumber().

QUESTION

Karma tests succeed but PhantomJS returns "An error was thrown in afterAll" SyntaxError: Unexpected token ','

Asked 2019-Jun-02 at 06:52

All our karma unit tests seem to succeed in our automated build, but the PhantomJS runner returns a non-zero result to the build framework (TeamCity). The only error I can find in the logs is:

Apparently PhantomJS hasn't been updated since 2016 (v2.1.1) and is not an active project. It seems that the recommendation is to replace PhantomJS in your projects with ChromeHeadless.

Even the PhantomJS maintainer, Vitaliy Slobodin, said about ChromeHeadless:

I think people will switch to it, eventually. Chrome is faster and more stable than PhantomJS. And it doesn’t eat memory like crazy.

It would have been nice to find a headless browser that wasn't dependent on Google, but apparently PhantomJS was using a WebKit-based engine anyway, so we're not really losing any browser variety/breadth by making this change.

Following the instructions in the linked articles, my issue went away, sort of. I did run into another similar afterAll error related to a missing library reference. I suspect that this was the same error as with PhantomJS but was not being reported correctly. After switching to ChromeHeadless, the error was reported correctly and was easy to fix.

QUESTION

Angular compiler can't find jasmine.CustomMatchers even though it's in the @types/jasmine

Asked 2019-Apr-28 at 19:41

I just downloaded example testing project from Angular guide: https://angular.io/generated/zips/testing/testing.zip

When I do ng serve I get errors:

src/testing/jasmine-matchers.d.ts(3,67): error TS2694: Namespace 'jasmine' has no exported member 'CustomMatcher'.

I am fairly new to Angular. Could someone help me understand what's wrong?

I have done npm install and when I go to node_modules/@types/jasmine I can see that CustomMatchers is defined in index.d.ts

Angular 7

Typescript 3.0

It turns out that the errors are caused by incompatible versions of Typescript and @types/jasmine packages. The following versions should work:

QUESTION

Cannot run tests (jasmine, karma, webpack)

Asked 2018-Apr-24 at 09:32

I've been trying for a couple of days now to get some tests to run.

I've two environments, one very "empty" and another with a full project. The 'empty' one does run a very simple test (but doesn't contain the Person object that is unable to be constructed in the full project).

I migrated the full project to a very similar environment in terms of installed dev packages, karma, jasmine versions and such. I also copied the tsconfig.json, karma.conf files across. Those are below.

For the life of me I cannot figure out why the karma tests will not run. With previous versions of Karma I would get an error along the lines of 'scheduler_person.b' is not a constructor.

Digging a little deeper, it's failing on this line of test.store.ts:

In src/providers/store/test.store.ts you need to move all of your global constants (and subsequent method calls) into the SetupStore method of the NPBCStoreConstruction class. When I do this I can run the test suite properly.

The cause of issue is that when Webpack/Typescript/something compiles everything, it picks an arbitrary order to include all the files and if you look at the generated code you can see that the global invocation of the person Person constructor happens before it is defined.
