What is database integration testing?

What is database integration testing?

Functional and Data Validation Tests – Checking to ensure data is loaded into the system according to the business rules. Data Integration Tests – Assessing the initial data loaded, as well as incremental data that continues to be loaded in real-time or frequently due to modifications, updates, and transformations.

Should integration tests use database?

You MUST write a real integration test anyway Even with writing in-memory tests, we still absolutely wrote integration tests against a real database. Those unit tests with in-memory looked exactly like the integration tests, just with a different provider.

What is in memory testing?

An in-memory database is a database that runs entirely in main memory, without touching a disk. Often they run as an embedded database: created when a process starts, running embedded within that process, and is destroyed when the process finishes.

How do I run an integration test faster?

In-memory databases such as H2, HSQLDB, and Derby are great to speed up integration tests. Although most database queries can be run against these in-memory databases, many enterprise systems make use of complex native queries which can only be tested against an actual production-like relational database.

What are the types of integration testing?

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.

How do you test data integration?

Integration Testing Steps:

1. Prepare Integration Test Plan.
2. Prepare integration test scenarios & test cases.
3. Prepare test automation scripts.
4. Execute test cases.
5. Report the defects.
6. Track and re-test the defects.
7. Re-testing & testing goes on until integration testing is complete.

How do you conduct a memory test?

Memory Test

1. Brief participants. Tell them that you are going to administer a memory test.
2. Present words. Read the following list of words.
3. Administer the recall test. Pause for about 10 seconds.
4. Explain your intent.
5. Debrief.
6. Encourage action planning.

Which tool can be used for integration testing?

Some of the most used integration testing tools are as follows: Citrus. FitNesse. TESSY.

Can you write integration tests against an in memory database?

First and foremost, an in-memory provider is a pale imitation for the real thing. Even with writing in-memory tests, we still absolutely wrote integration tests against a real database. Those unit tests with in-memory looked exactly like the integration tests, just with a different provider.

Can you write unit tests in addition to integration tests?

You can still write unit tests in addition to the integration tests. But you might end up testing the same things multiple times. Testing against the production database. The tests are even more meaningful because we are testing against the real database in the same version as in production.

Is the same in-memory database reused in all tests?

The same in-memory database is reused, but it is emptied to avoid tests working on data modified by other tests. The only aspect I do not particularly like is that the explicit Reset functionality in the actual test class, but it is very short and that code must be somewhere in the class anyway.

How are integration tests better than mock-based tests?

Instead, focus more on integration tests in which we wire the real objects together and write a single test that hits all layers. Advantages: We test behavior instead of an implementation. We test much closer to reality because in production the application will also use the real objects.
