Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.
Back To Main Menu Back To Main MenuWhat Is API Testing?
APIs, or Application Programming Interfaces, are what developers use to connect one application to another which allows for data exchanges between pieces of software. If an API doesn’t work efficiently or effectively, it can negatively impact software quality, business processes and the end user’s experience.
Most applications include three primary layers - the user interface (presentation), the business layer and the database which is used to categorize and manipulate the data.
QASource’s API Testing Services Include
A strong API testing process should include the types of tests highlighted below to ensure that all API performance, functionality and security features are in place. Our team at QASource also implements automated testing techniques to increase the efficiency and comprehension of API tests.
Functional Testing
Allow time for functional testing so you can properly validate the end to end functionality of your application and API layers.
Web UI Testing
This type of testing involves the graphical user interface and makes sure that the web application or website’s functionality and usability meet expectations.
Load Testing
Make sure the application and APIs perform as they should when under heavy number of users.
Runtime/Error Detection
This type of testing ensures that all exceptions and resource leaks are identified and corrected.
Security Testing
Ensure that common security features like authentication, permission settings and access controls meet the predefined requirements. Common security testing approaches include penetration and fuzz testing.
Validation Testing
Validation testing is one of the last types of testing that teams complete and ensures that API connections are working properly across the application. Validation testing typically includes a series of smaller tests which include unit, integration, system and UAT Testing.
Interoperability and WS Compliance Testing
Make sure that your SOAP APIs communicate correctly and efficiently with all other software components.
Automated API Testing
Having a team and technology in place that can automate a percentage of the tests, allow teams to scale quickly and ensure their APIs receive comprehensive testing.
API Testing Benefits
Ease of Access
API Testers can detect and correct errors earlier before they become larger issues.
Cost-Effective
Because API testing requires less coding, your team can enjoy faster test results more affordably.
Increased Security
The unique set of conditions and inputs within an API removes common vulnerabilities and adds more protection for an application.
Language Independent
An API test exchanges data using XML or JSON. These transfer modes are completely language-independent, meaning that you can select any core language when pursuing automated testing services for your application.
Simple Integration With GUI
Web API testing supports highly integrable tests, which are especially beneficial when your team executes functional GUI tests following your API testing process.
Less Time Consuming than Functional GUI testing
API testing allows teams to scale quickly and efficiently. Our team of experts project that 3,000 API tests can be completed in about 50 minutes, while 3,000 functional GUI tests will take approximately 50 hours.
Our API Testing Tools Include
There are a variety of API testing tools available to development and QA teams, but selecting the best set of tools can be a time consuming and difficult process. When you partner with QASource, our team of tool agnostic experts can help your team evaluate, choose and implement the most appropriate set of tools to complete your API testing needs.
