Application example of the newman framework in the Java library

The Newman framework is a Java test framework based on Junit, which is mainly applied to the unit test of the class library.It provides a series of assertions and test kits to help developers write reliable test cases and improve test coverage.Here are a Java class library application example using the Newman framework. Suppose we are developing a mathematical library that contains some common mathematical computing methods, such as additional methods and multiplication.We want to ensure the correctness of these methods and be able to perform comprehensive unit testing. First, we need to import the newman framework dependencies in the project.You can add the following dependencies to the construction document of the project: <dependency> <groupId>io.github.artsok</groupId> <artifactId>newman</artifactId> <version>5.3.0</version> <scope>test</scope> </dependency> Next, we create a class called Mathutils, which will include our mathematical operations.Below is an example code of the Mathutils class: public class MathUtils { public static int add(int a, int b) { return a + b; } public static int multiply(int a, int b) { return a * b; } } Now, we can write a test using the NEWMAN framework for unit testing.The following is an example code for mathutill tests written in the newman framework: import static io.github.artsok.Newman.*; public class MathUtilsTest { @Test public void testAdd() { int result = MathUtils.add(2, 3); // Use the newman to assert method to assert assertEquals(5, result); } @Test public void testMultiply() { int result = MathUtils.multiply(2, 3); // Use the newman to assert method to assert assertEquals(6, result); } @Test public void testAddAndMultiply() { int result = MathUtils.multiply(MathUtils.add(2, 3), 4); // Use the newman to assert method to assert assertEquals(20, result); } public static void main(String[] args) { // Use the newman test kit to run the test run(MathUtilsTest.class); } } In the above sample code, we wrote three test methods to test the correctness of the ADD and Multiply methods in the Mathutils class.In each test method, we use the Asseretequals method provided by the Newman framework to assert. Finally, in the Main method of the test class, we use the Run method of the Newman framework to run the test kit.This method will automatically execute all test methods marked as @Test. Using the Newman framework for unit testing can help us ensure the correctness of the code and provide reliable test coverage.By writing a comprehensive test case, we can easily discover and repair the potential bugs, thereby improving the quality and reliability of the code.
