The main aim of using a test fixture lies in the fact that there should be a familiar and fixed environment. Moreover, these tests are run so that the results are repeatable. It comprises of the following procedures.
1. The setup method which runs every test
2. The teardown procedure which runs after the execution of a particular test
Q11) Give a brief account of the Test Suite with respect to JUnit
Test Suite usually refers to the principle of compiling a variety of unit test cases to run it concurrently. In this context, it is interesting to note that in JUnit, both Run With and Suite comments are being used to avail maximum benefits.
Q12) What is a test fixture with respect to JUnit?
A test fixture is also known as a regulated state of objects that can be used as a platform for running the tests. The primary purpose is to make sure that there is a known climate in which the development tests can be run. Various examples can be cited in this context. They are as follows:
1. Copying the fixed known set of files
2. Preparing the input data and the creation of mock and fake objects
3. Assessing a database with fixed and known sets of data
It is also essential for you to note that if a group of tests shares the same fittings, one needs to write a different setup code. On the other hand, if the group of assessments is in need of a different test fixture, one can write the code alongside the test procedure. In this manner, one can create the best accessory related to a test.
Q13) Shed light on the reason that why JUnit only reports the first failure in a single attempt
It is interesting to note that saying multiple shortcomings in one attempt signifies that the test is of a larger size. This is the reason that JUnit is designed in such a manner that it usually runs on the smaller number of tests. Quite interestingly, it is capable of executing each assessment within the boundaries of a separate analysis. Moreover, it is also able to report the failures on each attempt of the tests.
Q14) Shed your views on the @ignore annotation. Even describe its usefulness
Here is the list of advantages of using this kind of annotation
1. It is important to note that one can easily find @ignore annotations with relatively much ease that lies inside the source code. On the other hand, the unannotated and uncommented tests are complicated to find.
2. Moreover, one may come across various situations where one cannot fix a code. However, if you still want that source method to be taken into account, @ignore annotation plays a crucial role in that.
Q15) What do you mean by parameterized tests in JUnit?
In the version 4 of JUnit, there is a new feature known as Parameterized Tests. These tests usually allow the developer to run the same amount of tests over and again. In this manner, the suitability of using various values increases considerably.
Q16) Describe the process which is helpful in the creation of parameterized Tests
In order to answer this question, you need to take into account that there are five steps. These steps are as follows:
- 1. The first step is that you have to create a public constructor which would take into account the equivalent value of a row of test related data
- 2. In the second step, you have to annotate the test class with a command by the name of @Run With
- 3. In the third step, you have to create a public static procedure which has the ability to return a collection of test data sets
- 4. In the fourth step, you need to create a viable which is instantaneous and is the source of data
- 5. In the last level, you have to make sure that test case is invoked only once per each row. This would facilitate the smooth running of an application.
Q17) Give a thorough analysis of the Joint Test API Methods
Here is the following list of the execution procedures which would help to analyze the problem. It is as follows:
1. In the first step, you need to use the annotation in the form of @before class
2. Secondly, make sure that you use the annotation @after class
3. Subsequently, before executing the test class, make sure that you use @before performs
4. Lastly, use @before so that the application development process is smooth and is hassle free
Q18) Shed light on the process of installing JUnit?
In order to install JUnit, you need to follow the below-mentioned procedures. They are as follows:
