how to write integration tests

How is Integration Testing Done?

1. Prepare the test integration plan.
2. Decide on the type of integration testing approach.
3. Design test cases, test scenarios and test scripts accordingly.
4. Deploy the chosen modules together and get the integration tests running.
5. Track the defects and record the test results of tests.

What is integration testing with example?

System Integration Testing is defined as a type of software testing carried out in an integrated hardware and software environment to verify the behavior of the complete system. ... For Example, software and/or hardware components are combined and tested progressively until the entire system has been integrated.

When should you write integration tests?

Usually, integration testing comes right after unit testing to ensure all units operate in harmony with each other. Oftentimes, a unit will be seen as functional on its own but may cause issues when interacting with other units. That's why software testing is so important, especially testing units as a group.

How do you write an integration test in Java?

1. Developers run the test goal during development.
2. Developers run the test goal before any commit.
3. Developers run the integration-test goal before a major commit with many side effects.
4. Build server compiles code and runs the test goal every 15-30 minutes (main build)

What are some integration testing methods?

Some different types of integration testing are big-bang, mixed (sandwich), risky-hardest, top-down, and bottom-up. Other Integration Patterns are: collaboration integration, backbone integration, layer integration, client-server integration, distributed services integration and high-frequency integration.

Who is responsible for integration testing?

Mostly done by developers but testers can also participate, focusing on important or complex modules. Integration testing - Done when two modules are integrated, in order to test the behavior and functionality of both the modules after integration.

When API testing is done?

API testing is a type of software testing that involves testing application programming interfaces (APIs) directly and as part of integration testing to determine if they meet expectations for functionality, reliability, performance, and security. Since APIs lack a GUI, API testing is performed at the message layer.

How do you speed up integration testing?

As you can see, you can do three simple things to speed up your integration tests using PostgreSQL:

1. Change default PostgreSQL settings to speed the database up.
2. Change your tests to run in parallel.
3. Run each test in one transaction.

How long should integration testing take?

I write quite thorough integration tests, trying to make sure I cover each feature. On travis-ci, the entire process takes 25-30 minutes to run (including installing the bundle).

What are the different levels of testing?

There are generally four recognized levels of testing: unit/component testing, integration testing, system testing, and acceptance testing. Tests are frequently grouped by where they are added in the software development process, or by the level of specificity of the test.

How load testing is done?

How to do Load Testing

1. Create a dedicated Test Environment for load testing.
2. Determine the following.
3. Load Test Scenarios.
4. Determine load testing transactions for an application. Prepare Data for each transaction. ...
5. Test Scenario execution and monitoring. ...
6. Analyze the results. ...
7. Fine-tune the System.
8. Re-test.

What is difference between unit test and integration test?

Unit Testing test each part of the program and shows that the individual parts are correct, whereas Integration Testing combines different modules in the application and test as a group to see they are working fine. ... Unit Testing is executed by the developer, whereas Integration Testing is performed by the testing team.

How do you write an integration test for REST API?

There are three basic layers of testing:

1. Unit test — making sure each function/unit of code works as expected.
2. Functional test — making sure units interact with each other as expected.
3. Integration test — making sure our app integrate with other app/api/services as expected.
