assertions

问题 I would like to use PHP's preg_replace() to search a text for occurrences of a certain word, and enclose that word in brackets, unless there are already brackets present. The challenge here is that I want to test for brackets that may or may not be directly adjacent to the text I am looking for. Random example: I want to replace warfarin with [[warfarin]] in this string: Use warfarin for the prevention of strokes but not in this string: Use [[warfarin]] for the prevention of strokes (brackets

问题 This question already has answers here : AssertContains on strings in jUnit (7 answers) Closed 6 years ago . I have done a lot of functional testing on text outputs on text generating software lately, an find myself writing a lot of assertTrue(actualString.contains(wantedString)); However, the message for when this fails is something non-descriptive like Expected [true], but was [false] An alternative is to include a custom fail message as String failMsg = String.format("Wanted string to

问题 I connect to my database with one session. I have always the same session in my whole program. My Thread "1" catches primary data from the database. The user must be allowed to cancel this thread. So if the user presses the cancel button to often or to fast (this is my interpretation) the following error occures: ERROR org.hibernate.AssertionFailure - HHH000099: an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session) org

问题 I want to assert that a method is called exactly one time. I'm using RhinoMocks 3.5. Here's what I thought would work: [Test] public void just_once() { var key = "id_of_something"; var source = MockRepository.GenerateStub<ISomeDataSource>(); source.Expect(x => x.GetSomethingThatTakesALotOfResources(key)) .Return(new Something()) .Repeat.Once(); var client = new Client(soure); // the first call I expect the client to use the source client.GetMeMyThing(key); // the second call the result should

问题 I'm pretty new to Java and am following the Eclipse Total Beginner's Tutorials. They are all very helpful, but in Lesson 12, he uses assertTrue for one test case and assertFalse for another. Here's the code: // Check the book out to p1 (Thomas) // Check to see that the book was successfully checked out to p1 (Thomas) assertTrue("Book did not check out correctly", ml.checkOut(b1, p1)); // If checkOut fails, display message assertEquals("Thomas", b1.getPerson().getName()); assertFalse("Book was

问题 I am not able to understand how to write Java code to implement Verify . I am always seeing the code to implement Assert but not for Verify . I know for Assert , we need to write the code as below: Assert.assertTrue() or Assert.assertEquals() etc. But what about Verify ? I want to verify the title of my application once the user is logged into the application by using verify . How can I do this? 回答1: You must use the TestNG framework which only supports Assert statements. It doesn't support

问题 When reading some documentation about assertions, I found: java -ea -dsa "Enables assertions in general, but disables assertions in system classes." Which are the system classes? 回答1: According to the assertions documentation, system classes are classes "which do not have an explicit class loader", i.e. the classes loaded by the bootstrap classloader. AFAIK that means the contents of rt.jar , the entire standard API. 回答2: Per the same documentation system classes are classes which do not have

问题 I use assertions in Java in a standard way, having them turned on in my IDE. So they are not part of production release. Lately I have been seeing code examples with throw new AssertionError() and I started thinking about the situation where AssertionError should be used instead of assertion. My guess is that main difference is the optionality of asserts so they don't slow down the production performance and so they can occur quite often in the code, but fixing hardly reproducible bugs
