How to create unit test for queueable apex?

Create an instance of the AddPrimaryContact class, enqueue the job and assert that a Contact record was inserted for each of the 50 Accounts with the BillingState of “CA”. The unit tests must cover all lines of code included in the AddPrimaryContact class, resulting in 100% code coverage.

Why is the addprimarycontacttest not using the class?

The ‘AddPrimaryContactTest’ test class doesn’t appear to be using the ‘AddPrimaryContact’ class. I am getting 100% code coverage for my class. I cleared the same error by removing the space in test class for below line.

Can you get httpresponse from a queueable class?

Since a queueable class doesnt return values, you can’t directly get HttpResponse by executing Queueable class. In a real-life scenario, a queueable class will make a callout, get response and update/create/delete a record. You can create response in such a way that the data is affected in an expected way.

How are static variables reset in apex Test class?

Static variables in an apex test class are reset between: every test method execution. every transaction boundary (specific to the apex jobs or future calls inside test class). Salesforce does this in order to maintain truly independent testing for each method or transaction boundary.

Is it bad practice to use shared state in unit tests?

Important: This answer applies to .NET Framework. For dotnet core, see Dimitry’s answer regarding xunit.runner.json. All good unit tests should be 100% isolated. Using shared state (e.g. depending on a static property that is modified by each test) is regarded as bad practice.

Why are unit tests executed serially in C #?

I have run into a difficulty in unit testing this host management engine, however, due to the way ServiceHost works. If a ServiceHost has already been created, opened, and not yet closed for a particular endpoint, another ServiceHost for the same endpoint can not be created, resulting in an exception.

How to stop parallel test execution in xUnit?

For .NET Core projects, create xunit.runner.json with: For .NET Core projects, you can configure xUnit with an xunit.runner.json file, as documented at https://xunit.github.io/docs/configuring-with-json.html. The setting you need to change to stop parallel test execution is parallelizeTestCollections, which defaults to true:

What kind of test is mocking unit test?

This kind of test is a State Test; call the method and check you receive the correct result. But here you want to perform an Interaction Test; one that tests that some methods were called correctly (you may not know what these methods do to the data, so you cannot test the result’s value consistently).

Is the test of this kind of class brings any value?

The test code of this method seems to be a simple repetition of the code itself, but more complex. Does the test of this kind of class whose role is to control other classes brings any value? Does it bring any value? Yes – it is testing interaction.

What kind of non primitives does queueable apex support?

Queueable apex supports non-primitives like SObject and custom Apex types. We can monitor the status and progress of Queueable method using the returned Id of AsyncApexJob.
