I am working on angular 6
I don't have any else statement in my below code.But I am unable to cover branches due to else path not taken .What I need to do to get 100% branch coverage in this case?
getHeaderDocumentList(documents: any) {
if (documents) {
documents.result.docAttachment.forEach(element => {
this.headerdocumentdetails.push(element.DocumentUniqueID);
});
}
}
In order to get full coverage reported, the code needs to eventually hit the (here non-explicitly-existent) else
-path. For that matter pass in a falsy
parameter like 0 | false | undefined | null | NaN | '' | "" | ``
as in
component.getHeaderDocumentList(false);
expect(false).toEqual(false); // This line is optional. Most test suites require some kind of assertion in each test.
Now your test-suite should report both branches as covered.
Last solution would be to add
/* istanbul ignore else */
in before the if case. That will tell the coverage reporter to effectively ignore the else path
