Java unit test coverage numbers do not match.
- by Dan
Below is a class I have written in a web application I am building using Java Google App Engine. I have written Unit Tests using TestNG and all the tests pass. I then run EclEmma in Eclipse to see the test coverage on my code. All the functions show 100% coverage but the file as a whole is showing about 27% coverage. Where is the 73% uncovered code coming from?
Can anyone help me understand how EclEmma works and why I am getting the discrepancy in numbers?

@PersistenceCapable(identityType= IdentityType.APPLICATION)
public class Account {
@PrimaryKey
@Persistent(valueStrategy=IdGeneratorStrategy.IDENTITY)
private Long id;

public Account() {}
public Account(String firstName, String lastName, String email) {
super();
this.firstName = firstName;
this.lastName = lastName;
this.email = email;
}
public Account(String userId) {
super();
this.userId = userId;
}
public void setId(Long id) {
this.id = id;
}
public Long getId() {
return id;
}
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public boolean acceptedTermsOfService() {
return termsOfService;
}
public void setTermsOfService(boolean termsOfService) {
this.termsOfService = termsOfService;
}
public boolean acceptedSystemEmails() {

public void setSystemEmails(boolean systemEmails) {
this.systemEmails = systemEmails;
}
}
Below is the test code for the above class.
