因此，对于我的编程类，我们应该为继承自抽象类的其中一个类进行Junit测试。我在编写Junit测试时感到非常困惑，因为我不觉得网上有足够的例子。我的第一个问题是，我们测试getter和setters吗？我的教授指示我们在设置我们的测试时“选择所有”方法，但在她要求我们阅读的网站上，他们建议不要测试getter和setter，因为JVM已经拥有测试人员。我的第二个也是最重要的问题是你可以测试一个完整的构造函数吗？我的下面的代码基本上有一个从抽象的学生类继承的本科生。我假设我应该测试以确保本科学生实际上是本科生，而不是硕士生，但我不知道如何精确测试整个构造函数。任何提示将非常感谢！！Junit测试构造函数
public abstract class AbstractStudent {
/**
* First name of a student.
*/
private String myFirstName;
/**
* Last name of a student.
*/
private String myLastName;
/**
* Student 9-digit ID.
*/
private String myID;
/**
* Number of credit hours completed by a student.
*/
private int myCreditHours;
/**
* Current student GPA.
*/
private double myGPA;
/**
* Student gender.
*/
private Gender myGender;
/** Student date of birth.
*
*/
private Date myBirth;
/**
* Private constructor to prohibit default instantiation.
*/
/**
* @param theFirstName Adds the first name into the constructor
* @param theLastName Adds the last name into the constructor
* @param theID Adds the ID into the constructor
* @param theCreditHours Adds the credit hours into the constructor
* @param theGPA Adds the GPA into the constructor
* @param theGender Adds the gender into the constructor
* @param theBirth Adds the birth into the constructor
*/
public AbstractStudent(final String theFirstName, final String theLastName,
final String theID, final int theCreditHours, final double theGPA,
final Gender theGender, final Date theBirth) {
myFirstName = theFirstName;
myLastName = theLastName;
myID = theID;
myCreditHours = theCreditHours;
myGPA = theGPA;
myGender = theGender;
myBirth = new Date(theBirth.getTime());
}
而且UndergradStudent类：
public class UndergradStudent extends AbstractStudent {
/**
* Student status.
*/
private StudentStatus myStatus;
/**
* Parameterized constructor - constructors a Student object.
* @param theFirstName is a string representing the first name of a student, != null
* @param theLastName is a string representing the last name of a student, != null
* @param theID is a string of 9 characters representing student ID
* @param theCreditHours is an integer number >=0 representing number of credit hours
* taken by a student
* @param theGPA is a double number representing GPA, a GPA must be >= 0 and <= 4.0
* @param theStatus is a string representing student status, != null
* @param theGender is a character representing student gender, != null
* @param theBirth is a date representing student birth date; a student cannot be younger
* than 10 years old
* @custom.post Student object constructed; if invalid parameters passed,
* student is in an invalid state.
*/
public UndergradStudent(final String theFirstName, final String theLastName,
final String theID, final int theCreditHours, final double theGPA,
final StudentStatus theStatus, final Gender theGender,
final Date theBirth) {
super(theFirstName, theLastName, theID, theCreditHours, theGPA, theGender, theBirth);
myStatus = theStatus;
}
在我看来，测试getter和setter并不重要，除非它们包含业务逻辑（这种逻辑不应该驻留在那里）。坚持测试应用程序重要部分的口头禅，而不是使代码覆盖率成为您的目标。 – JamesB
所以我可以创建一个包含整个构造函数的单个测试方法，或者你说我应该测试一些特定的领域例如：名字，姓氏，gpa等等。我只是觉得如果我为每个东西做了一个单独的测试方法，它会占用大量的空间。谢谢！ – user3376654
测试方法，而不是字段，不担心你有多少测试，只要确保他们正在测试不同的逻辑块。 – JamesB
