Knowledge quiz

It's time to put what you've learned to the test, get 7 right to pass this week.

When following the test-driven development approach, what should you do before you start developing a new product code?

Choose the correct answer.

Build a failing test so you can write the complete product code at once.

Write all tests before you write the first line of product code.

Formulate the first set of requirements you have for the product code in short sentences, which then translate into the test cases.

Delete the existing tests, so they do not interfere with your new code.

When following the test-driven development approach, can you finish the product code and postpone the test development?

Choose the correct answer.

Yes, but this requires additional development effort.

Yes, this is the recommended strategy.

No, test development must be completed at least one month before you begin code development.

No, your tests and your product code must be ready at the same time.

When following the test-driven development approach, how should you implement your tests?

Choose the correct answer.

Write at least two tests in parallel.

Write only one test at a time.

Implement all the written-down requirements in parallel.

Start each day with one test and finish them all by the end of the week.

Why is it so important to see a test fail at least once?

Choose the correct answer.

Because this calibrates the ABAP unit runtime

Because if you never see your test fail, this might be an indication that either your test verification is missing or it is erroneous

Because you can earn bonus points for each failing test

To remember you that success and failure are dependent on each other

When following the test-driven development approach, when are you allowed to switch from test development to product code development?

There are three correct answers.

At the latest after 15 minutes of test development

When you get a syntax error which needs to be fixed in the product code (for example, a missing method)

At any time once your test code line count is above 13

When your test case is complete and fails

When your test case demonstrates a failure

When following the test-driven development approach, when are you allowed to refactor the product code?

Choose the correct answer.

When you switch from test code to product code development

When all tests are green

When your current test case passes and at least one old test case fails

When an odd number of test cases fail

When strictly following the test-driven development approach, can you implement non-testable product code?

Choose the correct answer.

No, because product code is not testable by design

No, because the ABAP runtime makes sure all product code is testable

No, this is not possible because you write the test before the corresponding product code

No, because in this approach there is no product code at all

What is the meaning of the term "test-driven development"?

Choose the correct answer.

Test development drives feature development.

The test can be developed while driving.

The test drive proves the development.

Development drives testing.
