1.6. Testing the batch process

Batch applications are like any other applications: you should test them using a framework like JUnit. Testing makes maintenance easier and detects regressions after refactoring. Let’s test, then! This section covers how to write an integration test for a Spring Batch job. You’ll also learn about the launching API in Spring Batch. But don’t be too impatient—we need a couple of intermediary steps before writing the test: configuring a test infrastructure and showing you a trick to make the job configuration more flexible.

Spring Batch and test-driven development Good news: Spring Batch and test-driven development are fully compatible! We introduce here some techniques to test a Spring Batch job, and chapter 14 is dedicated to testing. We don’t show tests systematically in this book; otherwise, half of the book would contain testing code! We truly believe in test-driven development, so we test all the source code with automated tests. Download the source code, browse it, and read chapter 14 to discover more about testing techniques.
