Test Automation Pyramid
What is Test Automation Pyramid?
The "Test Pyramid" is an
analogy that guides us to bunch programming tests into pails of various
granularity. It additionally gives a thought of what number of tests we ought
to have in every one of these gatherings. Despite the fact that the idea of the
Test Pyramid has been around for some time, groups still battle to incorporate
it appropriately. This article returns to the first idea of the Test Pyramid
and shows how you can try this. It shows which sorts of tests you ought to be
searching for in the various degrees of the pyramid and gives common sense
models on how these can be executed.
Why is it required?
Developed programming requires testing
before it goes into generation. As the order of programming advancement
developed, programming testing approaches have developed as well. Rather than
having heaps of manual programming analyzers, advancement groups have moved
towards mechanizing the greatest segment of their testing endeavors. Computerizing
their tests enables groups to know whether their product is broken in only
seconds and minutes rather than days and weeks.
Advantage of Test Automation Pyramid
The radically shortened feedback circle
fuelled via automated tests goes inseparably with development practices,
consistent delivery, and DevOps culture. Having a powerful programming testing
approach enables groups to move quickly and with certainty.
In the event that you need to quit
fooling around about automated tests for your product, there is one key idea you
should think about: the test pyramid. Mike Cohn concocted this idea in his book
Succeeding with Agile. It's an incredible visual allegory educating you to
think regarding various layers of testing. It additionally reveals to you how
much testing to do on each layer.
Layers of Test Automation Pyramid
Mike Cohn's original test pyramid has
three layers that your test should consist of:
1.
Unit Tests
2.
Service Tests
3.
User Interface Tests
· Unit tests
The establishment of your test suite
will be comprised of unit tests. Your unit tests ensure that a specific unit
(your subject under trial) of your codebase fills in as planned. Unit tests
have the tightest extent of the considerable number of tests in your test
suite. The number of unit tests in your test suite will largely outnumber some
other sort of test.
· Service Tests
The majority of the modern applications
have support for ‘third party developers’ to assemble a system around the
application. This is conceivable by uncovering Application Programming
Interfaces (APIs)/web-administration for the outside world/third party
developers. These APIs have negligible reliance on the UI layer. Analyzers can
utilize these APIs to think of tests that can be utilized to confirm the
fundamental highlights of the product.
· User Interface Tests
UI tests test that the UI of your
application works accurately. User input should trigger the correct activities,
data ought to be displayed to the user, UI state should change true to form.
Tools and Libraries used in the test automation pyramid:
JUnit: test runner
Wiremock: for stubbing out external
services
Selenium: for writing UI-driven
end-to-end tests
REST-assured: for writing REST
API-driven end-to-end tests
Conclusion:
With the quickly changing business
situation, time to advertise is exceptionally basic and any delay could bring
about a noteworthy measure of misfortunes to the association. Rather than the
conventional testing model, Test Automation Pyramid testing can be utilized to
build efficient, lessen time-to-showcase, and improve the quality of the
finished result.
