```
public int count()
```
    Description copied from interface: TestChecks
    
    Return the number of checks in this test.
    
    Specified by:
    
    count in interface TestChecks<RegressionChecks>
    
    Returns:
    
    the count of checks in this object
  - add
```
public void add(Check check)
```
    Adds the given check to the sequence.
    
    Specified by:
    
    add in interface TestChecks<RegressionChecks>
    
    Parameters:
    
    check - the check object to add to this set of checks
    
    Throws:
    
    java.lang.IllegalArgumentException - if the argument's class is ExceptionCheck and this already contains such a check
  - checks
```
public java.util.Set<Check> checks()
```
    Get all non-exception checks and whether they are passing for this object.
    
    Specified by:
    
    checks in interface TestChecks<RegressionChecks>
    
    Returns:
    
    map of non-exception checks in this object. each mapped to true, indicating it is passing.
  - hasChecks
```
public boolean hasChecks()
```
    Indicates whether this object has checks.
    
    Specified by:
    
    hasChecks in interface TestChecks<RegressionChecks>
    
    Returns:
    
    true if there are regression checks or an expected exception, false otherwise
  - hasErrorBehavior
```
public boolean hasErrorBehavior()
```
    Indicate whether this object has any failing checks. (This is essentially asking whether this is an error revealing test.)
    
    Specified by:
    
    hasErrorBehavior in interface TestChecks<RegressionChecks>
    
    Returns:
    
    false, since all regression checks are passing
  - getExceptionCheck
```
public ExceptionCheck getExceptionCheck()
```
    Description copied from interface: TestChecks
    
    Return the exception check in this object if there is one.
    
    Specified by:
    
    getExceptionCheck in interface TestChecks<RegressionChecks>
    
    Returns:
    
    the expected exception check, null otherwise

    Specified by:
    
    commonChecks in interface TestChecks<RegressionChecks>
    
    Parameters:
    
    other - the TestChecks to compare with
    
    Returns:
    
    the checks common to this set of checks and those in other
  - hasInvalidBehavior
```
public boolean hasInvalidBehavior()
```
    Indicates whether this set of checks contains any invalid behaviors.
    Returns false because regression checks are not invalid.
