Method Detail

getPointsFromAnnotation

public static double getPointsFromAnnotation(java.lang.StackTraceElement[] stack)

Gets the number of points allocated to a test method, based on a stack trace from within the call to that method.

Returns:

The number of points allocated to the currently executing test method.

Throws:

Util.NoPointsException - if the stack trace is ambiguous.

java.lang.IllegalArgumentException - if there is no currently executing test method.

getPointsFromAnnotation

public static double getPointsFromAnnotation()

Gets the number of points allocated to the currently executing test method. This is done by searching the call stack for the first call that has a Points annotation.

Returns:

The number of points allocated to the currently executing test method.

Throws:

java.lang.IllegalArgumentException - if there is no currently executing test method, or if the stack trace is ambiguous.

roundPoints

public static java.math.BigDecimal roundPoints(double points)

Rounds a double point value to a BigDecimal suitable for printing.

warn

public static void warn(java.lang.String message)

Prints a warning message. Stderr is used, since stdout may be redirected.

getClassList

public static java.lang.Class<?>[] getClassList(java.lang.Object[] args)

Uses Java Reflection to ascertain the classes of each of the elements of args. Returns the list of classes. Translates all wrapper classes (e.g. Integer, Double, etc.) to their corresponding native primitive type. Limitations: Will not be appropriate to use if the method you are looking for actually takes in a Wrapper class as a parameter.
