ReferenceError: spyOnProperty is not defined error is coming on running test case.
I want to spyOn treatmentInstruction BehaviorSubjectthat is present in my service as mentioned below :
treatmentInstruction = new BehaviorSubject(this.myGlobalVar);
currentTreatmentInstruction = this.treatmentInstruction.asObservable();
spyOnProperty
was added on jasmine 2.6.0, be sure that you fulfill that requisite.
Since jasmine
is a dependency of karma-jasmine
update that instead. Looks like on old version of this library jasmine
was added as a peer dependency so it would be up to you to install the correct version of jasmine
.
按照“ @ types / jasmine”:“〜2.8.3”,“ jasmine-core”:“〜2.8.0”,
I had this issue, updating jasmine version didn't help. The problem came for jshint, in your test directory you must modify your .jshuntrc file : in "globals": { add => "spyOnProperty" : false
Worked for me
