Imagine we’re testing a filter function that takes a source array of objects and a string to match on. On line 7 is where the function is passed to map. Add an additional test which uses the testarray and tests the contains method by verifying it returns true when supplied a value that exists in the array.

To Check That Something Is Not In An Array Or Object, We Can Use Expect.not.arraycontaining And Expect.not.objectcontaining Respectively.

Note that the js files (which are to be tested) are mapped by their names. Array type must be a constant expression. A unit can be described as the smallest testable part of code in an application.

There is one restriction on array type. Unit testing is important to verify the behavior of the smallest units of code in your application. For example, index.js is mapped to index.test.js.

Unit Testing In Particular Is Possibly The Most Important.

For passing other data types like string, we can use either object type or can use nunit testcasesource. Array with only 1 element. This is the file that we’re going to be creating unit tests for.

Unit Testing Is Typically Performed By The Developer.
