lime (test framework)

lime is a unit testing and functional testing framework built specifically for the Symfony web application framework based on the Test::More Perl library.[2] The framework is designed to have readable output from tests, including color formatting, by following the Test Anything Protocol which also allows for easy integration with other tools.[2] lime tests are run in a sandbox environment to minimize test executions from influencing each other.[2] Though the lime testing framework is built for testing within Symfony, lime is contained within a single PHP file and has no dependency on Symfony or any other library.[1][2]

The alpha version of lime 2.0 was announced on November 10, 2009[3] and is compatible with Symfony 1.2 and lower.[4] Symfony 2.0 uses PHPUnit for testing instead of lime.[5]

Example

lime unit tests use the lime_test object to make assertions. The following is a basic example lime unit test to test PHP's built-in in_array function.

include(dirname(__FILE__) . '/bootstrap/unit.php'); // Include lime.

// Create the lime_test object for 10 number of assertions and color output.
$t = new lime_test(10, new lime_output_color());

// The test array.
$arr = array('Hello', 'World', 123,);

// Output a comment.
$t->diag('in_array()');

// Test to make sure in_array returns a boolean value for both values
// that are in the array and not in the array.
$t->isa_ok(in_array('hey', $arr), 'bool', '\'in_array\' did not return a boolean value.');
$t->isa_ok(in_array('Hello', $arr), 'bool', '\'in_array\' did not return a boolean value.');
$t->isa_ok(in_array(5, $arr), 'bool', '\'in_array\' did not return a boolean value.');
$t->isa_ok(in_array(FALSE, $arr), 'bool', '\'in_array\' did not return a boolean value.');

// Test to make sure in_array can find values that are in the array
// and doesn't find values that are not in the array.
$t->ok(!in_array('hey', $arr), '\'in_array\' found a value not in the array.');
$t->ok(!in_array(5, $arr), '\'in_array\' found a value not in the array.');
$t->ok(!in_array(FALSE, $arr), '\'in_array\' found a value not in the array.');
$t->ok(in_array('Hello', $arr), '\'in_array\' failed to find a value that was in the array.');
$t->ok(in_array('World', $arr), '\'in_array\' failed to find a value that was in the array.');
$t->ok(in_array(123, $arr), '\'in_array\' failed to find a value that was in the array.');

Version 2.0

The alpha version of lime 2.0 was announced on the Symfony blog on November 10, 2009.[6] The second version of lime was built to be as backward compatible with the first version as was possible - the two parts of lime 2.0 that are not compatible with lime 1.0 are the configuration of the test harness and the LimeCoverage class.[3] lime 2.0 includes support for xUnit output, source code annotations, parallel execution of tests, automatic generation of mock and stub objects, and operator overloading for data within tests.[3] Unlike the first version of lime, lime 2.0 does have some dependencies on Symfony.[5]
