Key methods
  • check::Test(label,expected,actual)→bool Simple 'do we get the expected result'
    • check::TestNot() is the negative truth of Test()
  • check::Is(label,type,variable)→bool type can be
    • 'string','null','array','boolean'
    • 'numeric' ie. is numeric or convertable to a number
    • A class name (case sensitive)
  • check::Trap(label,message,function name,Object,Arguments)→bool Testing for exception handling
    • label is test identifier
    • message
      • If there shouldn't be an exception then an empty string
      • Otherwise some text fragment found in exception message
      • Note this works exclusively on exception message not exception 'type'(sub-class)
    • function name is a string being the name of the function or method to be executed
    • Object will be null if this is working on a plain function
    • Arguments is missing, a scalar (if only one argument) or an array of arguments
    • Examples
      • ('Zdiv','zero','Divide',$myObject,array(5,0)) // expects to trigger divide by zero
      • ('Feline.a','','AddToList',null,'cat') // this shouldn't be an exception
      • ('Feline.b','not a cat','AddToList',null,array('dolphin')) // triggers exception
  • check::Finish([fileName]) Prints full totals and timestamp. Optionally send output to file instead. The following tokens can be embedded. #n : Basename of test script. #d : DDYYMM #t : HHMMSS #f : Fail count. eg check::Finish('#nResults.htm');
Other test methods
  • check::Show(label,variable) Dump of variable.
  • check::TestNot(label,expected,actual)→bool
    Inverse truth of Test(). Used where you know of a result you don't want.
  • check::Label(label,[NewLineAfter=false])
    Writes just a label to the results. Optionally followed by new line.
Blocks of tests
The normal structure is repeating StartBlock()...tests ...EndBlock() followed by a final Finish() It is recommended to follow this pattern. Flush() shouldn't normally be required.
  • check::StartBlock(text,[buffering=true])
    • Text heading at the start of a block of tests.
    • Buffering defaults to true but may be set false if you want immediate reporting.
    • Note This doesn't reset counters
  • check::EndBlock()
    • Block summary
    • This resets counters
    • See check::ShowOkBlockDetails() below
  • check::AnyFailures() Boolean true if any failures in this block ie. since start or last Summary()
  • check::ShowOkBlockDetails(Show_flag) Call with false to suppress display of individual tests if a block has no failures. Default is true.
Verbosity adjustment
  • check::PassNone() Test functions still return truth values
  • check::PassDot() Dot with no new line
  • check::PassOk() 'ok' and new line
  • check::PassShort() label, ok and new line
  • check::PassLong() label, variable, new line
  • check::FailTiny() label and FAIL and new line
  • check::FailShort() label, FAIL, variable dumped and new line
  • check::FailLong() label, FAIL, variable dumped, message and new line
  • You need require_once('check.php'); at the top of your code.
  • dump.php needs to be in yor include path
  • check::Help() displays this information
  • Version as file date.

Example function FailOnNegative($Arg){ if($Arg<0){ throw new Exception('Negative not allowed'); } } check::PassLong(); check::StartBlock('Checking examples'); check::Is('E1.a','numeric',Time()); check::Test('E2.a','2011',Date('Y')); check::Trap('E3.a','Negative','FailOnNegative','',-5); check::EndBlock(); // more StartBlock()...tests...EndBlock() blocks might go here check::Finish();
