OSGI Enroute Hamcrest Wrapper framework advantages and functional characteristics introduction

OSGI Enroute Hamcrest Wrapper is a Hamcrest Wrapper framework based on OSGI Enroute.It provides a set of convenient and powerful assertions for verifying expected behaviors and structures in testing. Advantage: 1. Simplified test: Using OSGI Enroute Hamcrest Wrapper, you can verify the expected behavior by writing a simple and simple assertion code.It provides a variety of assertions, which can easily verify the equal nature of the object and the inclusion of the collection. 2. Provide a custom matching device: In addition to the predetermined assertions, Hamcrest also supports the custom matching device, making the test more flexible and scalable.By writing a custom matching device, the specific attributes or state of the data can be verified according to specific needs. 3. Strong readability: OSGI Enroute Hamcrest Wrapper provides a streaming grammar style to write an assertion.This style makes the test code more readable, and can express the expected behavior more clearly. 4. Easy integration: Because OSGI Enroute Hamcrest Wrapper is a framework based on OSGI Enroute, it can easily integrate with existing OSGI applications.This makes it very simple to add tests in existing applications. Features: 1. Equivalence: You can use the EQUALTO () method to assert whether the two objects are equal. assertThat(actualValue, equalTo(expectedValue)); 2. Collection assertion: You can use the Hasitem () method to assert whether there are specific elements in the set. assertThat(collection, hasItem(expectedElement)); 3. String matching assertion: You can use the containsstring () method to assert whether the string contains a specific sub -string. assertThat(string, containsString(substring)); 4. Custom matching device: You can use a custom matching device to verify the specific properties or state of the data. assertThat(object, customMatcher()); 5. Compound assessment: You can use methods such as allof (), anyof (), and not () to make composite assertions to achieve more complicated verification. assertThat(actualValue, allOf(notNullValue(), greaterThan(expectedValue))); Summarize: OSGI Enroute Hamcrest Wrapper is a powerful assertion framework. It provides a simple and readable assertion method and custom matching device, making the test simpler and flexible.Its characteristics include equal breaks, assembly assertions, string matching assertions, custom matching and composite assertions.Whether it is a new or existing OSGI application, you can easily integrate and use OSGI Enroute Hamcrest Wrapper to achieve efficient testing.
