Method Detail

prepare

public static void prepare(hudson.model.AbstractProject<?,?> project)
                    throws IOException

Prepares a new project to be measured. Usually called before starting builds, but may also be called retroactively.

Parameters:

project - a project of any kind

Throws:

IOException - if preparations fail

countLoads

public static int countLoads(hudson.model.AbstractProject<?,?> project,
             Runnable thunk)

Counts how many build records are loaded as a result of some task.

Parameters:

project - a project on which prepare(hudson.model.AbstractProject<?, ?>) was called prior to creating builds

thunk - a task which is expected to load some build records

Returns:

how many build records were actually loaded as a result

assertMaxLoads

public static <T> T assertMaxLoads(hudson.model.AbstractProject<?,?> project,
                   int max,
                   Callable<T> thunk)
                        throws Exception

Asserts that at most a certain number of build records are loaded as a result of some task.

Type Parameters:

T - the return value type

Parameters:

project - a project on which prepare(hudson.model.AbstractProject<?, ?>) was called prior to creating builds

max - the maximum number of build records we expect to load

thunk - a task which is expected to load some build records

Returns:

the result of the task, if any

Throws:

Exception - if the task failed

AssertionError - if one more than max build record is loaded
