DESCRIPTION

31       This module provides some tools for testing Alien::Build and alienfile.
32       Outside of Alien::Build core development, It is probably most useful
33       for Alien::Build::Plugin developers.
34
35       This module also unsets a number of Alien::Build specific environment
36       variables, in order to make tests reproducible even when overrides are
37       set in different environments.  So if you want to test those variables
38       in various states you should explicitly set them in your test script.
39       These variables are unset if they defined: "ALIEN_BUILD_PRELOAD"
40       "ALIEN_BUILD_POSTLOAD" "ALIEN_INSTALL_TYPE".

FUNCTIONS

43   alienfile
44        my $build = alienfile;
45        my $build = alienfile q{ use alienfile ... };
46        my $build = alienfile filename => 'alienfile';
47
48       Create a Alien::Build instance from the given alienfile.  The first two
49       forms are abbreviations.
50
51        my $build = alienfile;
52        # is the same as
53        my $build = alienfile filename => 'alienfile';
54
55       and
56
57        my $build = alienfile q{ use alienfile ... };
58        # is the same as
59        my $build = alienfile source => q{ use alienfile ... };
60
61       Except for the second abbreviated form sets the line number before
62       feeding the source into Alien::Build so that you will get diagnostics
63       with the correct line numbers.
64
65       source
66           The source for the alienfile as a string.  You must specify one of
67           "source" or "filename".
68
69       filename
70           The filename for the alienfile.  You must specify one of "source"
71           or "filename".
72
73       root
74           The build root.
75
76       stage
77           The staging area for the build.
78
79       prefix
80           The install prefix for the build.
81
82   alienfile_ok
83        my $build = alienfile_ok;
84        my $build = alienfile_ok q{ use alienfile ... };
85        my $build = alienfile_ok filename => 'alienfile';
86        my $build = alienfile_ok $build;
87
88       Same as "alienfile" above, except that it runs as a test, and will not
89       throw an exception on failure (it will return undef instead).
90
91       [version 1.49]
92
93       As of version 1.49 you can also pass in an already formed instance of
94       Alien::Build.  This allows you to do something like this:
95
96        subtest 'a subtest' => sub {
97          my $build = alienfile q{ use alienfile; ... };
98          alienfile_skip_if_missing_prereqs; # skip if alienfile prereqs are missing
99          alienfile_ok $build;  # delayed pass/fail for the compile of alienfile
100        };
101
102   alienfile_skip_if_missing_prereqs
103        alienfile_skip_if_missing_prereqs;
104        alienfile_skip_if_missing_prereqs $phase;
105
106       Skips the test or subtest if the prereqs for the alienfile are missing.
107       If $phase is not given, then either "share" or "system" will be
108       detected.
109
110   alien_install_type_is
111        alien_install_type_is $type;
112        alien_install_type_is $type, $name;
113
114       Simple test to see if the install type is what you expect.  $type
115       should be one of "system" or "share".
116
117   alien_download_ok
118        my $file = alien_download_ok;
119        my $file = alien_download_ok $name;
120
121       Makes a download attempt and test that a file or directory results.
122       Returns the file or directory if successful.  Returns "undef"
123       otherwise.
124
125   alien_extract_ok
126        my $dir = alien_extract_ok;
127        my $dir = alien_extract_ok $archive;
128        my $dir = alien_extract_ok $archive, $name;
129        my $dir = alien_extract_ok undef, $name;
130
131       Makes an extraction attempt and test that a directory results.  Returns
132       the directory if successful.  Returns "undef" otherwise.
133
134   alien_build_ok
135        my $alien = alien_build_ok;
136        my $alien = alien_build_ok $name;
137        my $alien = alien_build_ok { class => $class };
138        my $alien = alien_build_ok { class => $class }, $name;
139
140       Runs the download and build stages.  Passes if the build succeeds.
141       Returns an instance of Alien::Base which can be passed into "alien_ok"
142       from Test::Alien.  Returns "undef" if the test fails.
143
144       Options
145
146       class
147           The base class to use for your alien.  This is Alien::Base by
148           default.  Should be a subclass of Alien::Base, or at least adhere
149           to its API.
150
151   alien_build_clean
152        alien_build_clean;
153
154       Removes all files with the current build, except for the runtime
155       prefix.  This helps test that the final install won't depend on the
156       build files.
157
158   alien_clean_install
159        alien_clean_install;
160
161       Runs "$build->clean_install", and verifies it did not crash.
162
163   alien_checkpoint_ok
164        alien_checkpoint_ok;
165        alien_checkpoint_ok $test_name;
166
167       Test the checkpoint of a build.
168
169   alien_resume_ok
170        alien_resume_ok;
171        alien_resume_ok $test_name;
172
173       Test a resume a checkpointed build.
174
175   alien_rc
176        alien_rc $code;
177
178       Creates "rc.pl" file in a temp directory and sets ALIEN_BUILD_RC.
179       Useful for testing plugins that should be called from
180       "~/.alienbuild/rc.pl".  Note that because of the nature of how the
181       "~/.alienbuild/rc.pl" file works, you can only use this once!
182
183   alien_subtest
184        alien_subtest $test_name => sub {
185          ...
186        };
187
188       Clear the build object and clear the build object before and after the
189       subtest.
