Question
Question 2When the following test executes, what format will the result be?function subtract(a, b) { return a - b; } expect(subtract(10, 4)).toBe(6); 1 pointTrue/FalseSuccess/FailFunctionString3.Question 3True or Fals
Solution
The question seems to be incomplete. However, I can answer the first part of it.
The test function subtract(a, b) is expected to return the result of the subtraction of two numbers. In the test case provided, subtract(10, 4), the expected result is 6.
The expect().toBe() function is a part of Jest testing framework in JavaScript. It checks if the result of the function matches the expected output. If the result matches the expected output, the test will pass, otherwise, it will fail.
So, when the test executes, the result will be in the format of Success/Fail. If the function subtract(10, 4) returns 6, the test will be a success. If it returns anything other than 6, the test will fail.

What are the results of test case execution? There is an explicit message that test case execution has caused an error in the program. There is an explicit message that there is no error from the test case. The test case has either passed or failed. The program produces an output that is the same as the expected output.
