The purpose of end-to-end testing is testing whole software for dependencies, data integrity and communication with other systems, interfaces and databases to exercise complete production like scenario. Along with the software system, it also validates batch/data processing from other upstream/downstream systems. Hence, the name “End-to-End”.
Whatever your development methodology or techniques, database testing remains as complex as database development and deserves the necessary resources. Below we’ll have a look at four database testing types, namely user acceptance testing, integration testing, regression testing, and unit testing, and how they relate to MongoDB where applicable.
This test will use the real dependencies in the tests. Therefore, compared with unit tests, integration tests are more complex to write and debug (if tests fail). Integration tests also take more time to run and maintain. . In some cases, the QA team can do integration testing without understanding the code.
Integration testing traps. For me there are two big pitfalls when we are writing integration testing: 1. Try to test all application behaviours. As I said in the topic above, this is not the Only after the testing of that new feature is over does the next phase of the V model start. The V model in Software testing is useful for providing a systematic and visual representation of the SDLC process in a sequential manner. The shape ‘V’ represents the development and testing phase occurring together before moving on to the next stage. Now our integration test will always use the in-memory database provided by Entity Framework Core which we can safely recreate on every test. Note: As per the official docs, the in-memory database is not a full relational database and some features won’t be available like checking for referential integrity constraints when saving new records. .
