API Testing

// what we offer

API testing is a type of software testing that analyzes an application program interface (API) to verify it fulfills its expected functionality, security, performance and reliability. The tests are performed either directly on the API or as part of integration testing.

// WHAT WE DO

Our API Testing Services

‍Unit testing

Unit testing are tests that are written to automatically run with every build of the application. They are written close to the code and should pass when running a build of the application. What type of code coverage is required for the APIs depends on the risk the API carries and what functionalities it holds. Good unit testing is like a good foundation and this aspect should be well thought over as it will carry the rest of the testing effort later down the line.

Integration Testing

Our APIs are no separated component of a system. Instead they work to integrate all of the moving parts of a system and all of this integration requires proper testing of course. Not only do we need to make sure we are passing on and taking in the correct parameters with their correct constraints but we also need to make sure that we sanitize the incoming traffic in a logical way.

Performance testing

Performance testing is one of the non-functional things that is most often overlooked and will most often cause trouble. Be very aware that our testing environments often only contain a fraction of the data that production does so any process that runs might take a lot more time in a real scenario.

Load testing

Load testing is very similar to performance testing because we are trying to emulate production like traffic but instead of creating spikes in traffic we want to emulate a constant steady stream of traffic at a normally expected rate. This is to ensure that the API's do not contain memory leaks or other similar defects that might cause issues after running for a prolonged period of time.

Runtime error detection

During all of these tests, we want to make sure that we have Runtime error detection enabled. This technology allows our APIs to report back any defects that occur while it's in operation.

Security testing

This type of testing is very important but often not budgeted well. We need to ensure that proper security testing occurs based on a risk analysis. This type of testing needs to occur by a trained professional as it's very easy to miss things but it does not stop there. Every developer should in essence be a little bit of a security tester when it comes to APIs as they are often the first line of defense into our infrastructure.

Interoperability testing

Working with 3rd party software providers or even older versions of our software is not something we can take for granted. We need to create a section in our test plan where we describe what testing will be done. Severity and priority of potentials defects need to be discussed based on prior experiences and they need to help define how API testing occurs when the APIs interact with

Fuzz tests

s a final test before we validate our application we need to fuzz all the endpoints of our APIs. When fuzzing we will send random data to those API endpoints and we need to carefully inspect the results. Our server should not crash from this unexpected traffic and it should not display any odd behavior.

Validation Testing

During validation testing we need to ensure that the software meets the business requirements. The testers need to evaluate if the test execution results match what is expected and required by the test plan. They will subsequently guide the business users in their User Acceptance Testing (UAT) in which they ensure the stakeholders execute the pre-built testing scenarios and report any deviations on what was expected. If the software is approved.
