Test::Inline::Section - Implements a section of tests
This class implements a single section of tests. That is, a section of POD beginning with
=begin test or
There are two types of code sections. The first, beginning with
=begin testing ..., contains a set of tests and other code to be executed at any time (within a set of specifyable constraints). The second, labelled
=begin testing SETUP, contains code to be executed at the beginning of the test script, before any of the other sections are executed. This allows any needed variables or environment to be set up before the tests are run. You can have more than one setup section, and they will be written to the test file in order of appearance.
Some examples of the different types of test headers are as follows.
# Normal anonymous test =begin testing ok( $foo == $bar, 'This is a test' ); =end testing # A named test. Also provides the number of tests to run. # Any test section can specify the number of tests. =begin testing my_method 1 ok( $foo->my_method, '->my_method returns true' ); =end testing # A named test with pre-requisites. # Note that ONLY named tests can have pre-requisites =begin testing this after my_method foo bar other_method Other::Class ok( $foo->this, '->this returns true' ); =end testing
The first example shows a normal anonymous test. All anonymous test sections are considered low priority, and we be run, in order of appearance, AFTER all named tests have been run.
Any and all arguments used after "testing" must be in the form of simple space seperated words. The first word is considered the "name" of the test. The intended use for these is generally to create one named test section for each function or method, but you can name them as you please. Test names must be unique, and are case sensitive.
After the name, you can provide the word "after" and provide a list of other named tests that must be completed first in order to run this test. This is provided so that when errors are encounted, they are probably the result of this method or set of tests, and not in some other method that this one relies on. It makes debugging a lot easier. The word after is only a keyword when after the test name, so you can use a test name of after as well. The following are both legal
=begin testing after after that =begin testing this after after
The easiest and recommended way of labeling the tests is simple to name all tests after their methods, and put as a pre-requisite any other methods that the method you are testing calls. Test::Inline will take care of writing the tests to the test script in the correct order. Please note you can NOT define circular relationships in the prerequisites, or an error will occur.
If a number is provided as the last value, it will be taken to mean the number of actual tests that will occur during the test section. While preparing to write the test files, the processor will try to use these to try to determine the number of files to write. If ALL test sections to be written to a particular file have a test count, then the script will use the total of these as a basic for providing Test::More with a plan.
If ANY test sections to be written to a file do not have a test count, the test file with use
Finally, Test::Inline will try to be forgiving in it's parsing of the tests. any missing prerequisites will be ignored. Also, as long as it does not break a prerequisite, all named tests will be attempted to be run in their order of appearance.
my $Section = Test::Inline::Section->new( $pod );
new constructor takes a string of POD, which must be a single section of relevant pod ( preferably produced by Test::Inline::ExtractHandler ), and creates a new section object for it.
Returns a new
Test::Inline::Section object if passed POD in the form
=begin testing .... Returns
undef on error.
my $SectionList = Test::Inline::Section( @elements );
Since version 1.50 Test::Inline has been extracting package statements so that as the sections are extracted, we can determine which sections belong to which packages, and seperate them accordingly.
parse method takes all of the elements from a file, and returns all of the Sections. By doing it here, we can track the package context and set it in the Sections.
my $run_first = $Section->setup;
setup accessor indicates that this section is a "setup" section, to be run at the beginning of the generated test script.
Returns true if this is a setup section, false otherwise.
my $just_compile = $Section->example;
example accessor indicates that this section is an "example" section, to be compile-tested instead of run.
Returns true if this is an example section, false otherwise.
context method returns the package context of the unit test section, or false if the unit test section appeared out of context.
name method returns the name of the test section, or false if the test if anonymous.
tests method returns the number of Test::Builder-compatible tests that will run within the test section. Returns
undef if the number of tests is unknown.
For use mainly in debugging, the
begin method returns the literal string of the begin line/paragraph.
my $is_anonymous = $Section->anonymous;
anonymous method returns true if the test section is an unnamed anonymous section, or false if it is a named section or a setup section.
my @names = $Section->after;
after method returns the list of other named tests that this test section says it should be run after.
Returns a list of test name, or the null list
() if the test does not have to run after any other named tests.
my @classes = $Section->classes;
classes method returns the list of test classes that the test depends on, and should be run before the tests. These values are used to determine the set of class-level dependencies for the entire test file.
Returns a list of class names, or the null list
() if the test does not have any class-level dependencies.
my $code = $Section->content;
content method returns the actual testing code contents of the section, with the leading
=begin and trailing
Returns a string containing the code, or the null string
"" if the section was empty.
