junit

问题 I write jUnit test cases for 3 purposes: To ensure that my code satisfies all of the required functionality, under all (or most of) the input combinations/values. To ensure that I can change the implementation, and rely on JUnit test cases to tell me that all my functionality is still satisfied. As a documentation of all the use cases my code handles, and act as a spec for refactoring - should the code ever need to be rewritten. (Refactor the code, and if my jUnit tests fail - you probably

问题 I am new to Intellij IDEA. I have a POM based cucumber-selenium project, where I've created cucumber runner classes for each feature file. While working with Eclipse I was able to execute these runner classes by Right click. However in Intellij IDEA (licensed version), even when cucumber-for-java and junit plugins are enabled in Settings window, I dont get Run option. Also in Run/Debug configurations window -> Cucumber java -> what should be the main class? My main class has code to launch

问题 I wanted to choose the order to execute the JUnit tests. I have 4 classes with several test methods in it, my goal is to execute, for instance, method Y of class A, then method X from class B, and finally method Z from class A. Would you help please? 回答1: In general, you can't specify the order that separate unit tests run in (though you could specify priorities in TestNG and have a different priority for each test). However, unit tests should be able to be run in isolation, so the order of

问题 I'm trying to run a cucumber test with JUnit and I'm getting java.lang.NoClassDefFoundError exception. JUnit code: package ctest; import org.junit.runner.RunWith; import cucumber.api.CucumberOptions; import cucumber.api.junit.Cucumber; @RunWith(Cucumber.class) @CucumberOptions( features = "Feature" ,glue={"stepDefinition"} ) public class Runner { } Exception: java.lang.NoClassDefFoundError: gherkin/formatter/Formatter at java.lang.ClassLoader.defineClass1(Native Method) at java.lang

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed last year . What is the use of a Junit @Before and @Test annotations in java? How can I use them with netbeans? 回答1: Can you be more precise? Do you need to understand what are @Before and @Test annotation? @Test annotation is an annotation (since JUnit 4) that indicates the attached method is

问题 As part of Java code some task needs to be done tomorrow in JUnit. For example there are 3 tasks: task1 - done task2 - do it tomorrow task3 - then this will happen So as per requirement I need to set today's date as tomorrow in Java. 回答1: The root of your problem is that the system clock (what gives you the time in a new Date () ) is not giving you the time you need for your test. You can avoid this problem by introducing a level of indirection. Instead of having your code directly ask the

问题 What's the proper way of initializing the JavaFX runtime so you can unit test (with JUnit) controllers that make use of the concurrency facilities and Platform.runLater(Runnable) ? Calling Application.launch(...) from the @BeforeClass method results in a dead lock. If Application.launch(...) is not called then the following error is thrown: java.lang.IllegalStateException: Toolkit not initialized at com.sun.javafx.application.PlatformImpl.runLater(PlatformImpl.java:121) at com.sun.javafx

问题 I've recently become aware of powermock's Whitebox functionality. (In summary, it allows you to directly test private methods or modify private members directly from unit tests--while keeping them private!) I know that there are some frames of thought that frown upon unit testing anything other than visible methods, but darn it, sometimes you just want a simple test to ensure a deep level helper method is doing what it is supposed to do...without going through what could be huge overhead to

问题 import java.util.regex.Pattern; public class TestUI { private static Pattern p = Pattern.compile("^[A-Za-z0-9()+-]+$"); public static void main(String[] args) { // Test case1 String[] str=test(); System.out.println(str[0]+str.length); match("Alphanumeric(Text)"); } private static String[] test() { boolean res; String[] array={"a","b","c","d","e"}; for(int i=0;i<array.length;i++){ System.out.println(match(array[i])); res=match(array[i]); if(res=true) calltomethod(array); } return array; }

问题 I have a test case that requires typing in a partial value into an ajax based textfield and verifying the list has the expected content. If it does, select the content. Any idea how to make this work? 回答1: The type command may not be enough to trigger the autocomplete. Dave Webb's suggestions are otherwise spot on. My only addition would be that you might need the typeKeys command, which causes slightly different JavaScript events to be fired, which may be more likely to trigger the
