Here are three main types of tests we apply the API expert
with our clients and recommend to others.
• Functional Testing
Functional tests validate the software system to functional
specifications and requirements. Functional testing test API offers benefits in
a way that aims to test the application. To test each function of the API, QA
testers provide input appropriate parameters in the XML or JSON payload and
verifies the output of the functional requirements.

Kind of black-box testing are not concerned with the source
code of the application but the API function. The benefits of automation API in
our test was the response code delivery speed can be received in just one
millisecond!
• Security Testing
API security testing revealed risks, vulnerabilities or
threats in the API. Security testing to identify all potential loopholes and
weaknesses API that may lead to loss of information, revenue and reputation if
misused by unauthorized users. After all, what is the test API for if not to
prevent malicious attacks from internal users or disrupt the criminals?

Seeing the benefits of security testing API to check the
authentication requirements and confirm the encryption of sensitive data via HTTP.
Including penetration testing and testing fur so that your team can validate
methodologies encryption and authorization checks for access to resources.
• Load Testing
load test API API review performance under certain loads and
check how well behaved the API with multiple users simultaneously access the
system. API tests confirmed the expected load of an API to the right data and
that number is uncertain.
Seeing the benefits of test automation API to evaluate how
much traffic your system can handle before it becomes overloaded. That way,
your team can finish how you handle the software application traffic overloaded
before market launch.
Advantages of API Testing
Before we explore all the advantages of testing the API,
let's first compare the differences between API and GUI testing (or testing
graphical user interface). We must not overlook the advantages of testing
GUI-after all, it is very important to test how your customers interact with
your application's user interface. That being said, the main advantage of using
API testing can increase the coverage test cycle, conserve resources and
produce faster, more efficient releases.

Based on the timeline of your project, integration
requirements and the desired function, the benefits of testing six API can
contribute to the results of your product, consumer engagement and security:
1. Without Access UI
The main advantage of testing the API is to have access to
the application with no user interface or the user to interact with the system.
In other words, QA testers can run tests API without the need to undergo
software applications. This is a major advantage because it gives QA engineers
early insight into defects and errors that developers can resolve problems
before they impact the GUI.
2. Test for Core Functions
Test the code-level functions provide an initial evaluation
of the application to build overall strength before the test run the GUI. This
helps expose the small mistakes that can fester and become a bigger problem
during testing GUI. core access allows testing in line with the development,
encouraging improved communication and collaboration between the two teams.
This is especially beneficial if you do your API testing with QA teams
offshore.

3. Effective Time
One major difference between the API and GUI testing is that
testing of the API is much less time consuming than the functional GUI testing
time. And what best-known API testing but the speediness
of the results!
Just how much time can be saved by testing the API core
functionality of your application? Consider the real-life example is calculated
by our engineering team:
3000 API test at 50 minutes (in the parallel execution)
GUI 3,000 tests in 30 hours (in the parallel execution)
Your QA team to test the UI can expect comparable time
savings. Because the API test automation requires less code, testing the API
provides a better, faster test coverage of the automated GUI tests. The final
result of the rapid test is the overall testing costs reduced.
4. Language-Independent
As mentioned earlier, the test data exchange using XML or
JSON API. transfer mode is completely language-independent, which means that
you can select the core language while pursuing automated testing service for
your application.
5. Easy Integration With the GUI
By testing the API, integrating throughout the test very
possible. This is particularly useful if you plan to perform the following
functional GUI test your API testing. For example, easy integration will allow
for the creation of new users in the application before the commencement of the
test GUI.
