+ <title>Cross cover analysis</title>
+ <p>The cross cover mechanism allows cover analysis of modules
+ across multiple tests. It is useful if some code, e.g. a library
+ module, is used by many different tests and the accumulated cover
+ result is desirable.</p>
+
+ <p>This can of course also be achieved in a more customized way by
+ using the <c>export</c> parameter in the cover specification and
+ analysing the result off line, but the cross cover mechanism is a
+ build in solution which also provides the logging.</p>
+
+ <p>The mechanism is easiest explained via an example:</p>
+
+ <p>Let's say that there are two systems, <c>s1</c> and <c>s2</c>,
+ which are tested in separate test runs. System <c>s1</c> contains
+ a library module <c>m1</c> which is tested by the <c>s1</c> test
+ run and is included in <c>s1</c>'s cover specification:</p>
+
+<code type="none">
+s1.cover:
+ {incl_mods,[m1]}.</code>
+
+ <p>When analysing code coverage, the result for <c>m1</c> can be
+ seen in the cover log in the <c>s1</c> test result.</p>
+
+ <p>Now, let's imagine that since <c>m1</c> is a library module, it
+ is also used quite a bit by system <c>s2</c>. The <c>s2</c> test
+ run does not specifically test <c>m1</c>, but it might still be
+ interesting to see which parts of <c>m1</c> is actually covered by
+ the <c>s2</c> tests. To do this, <c>m1</c> could be included also
+ in <c>s2</c>'s cover specification:</p>
+
+<code type="none">
+s2.cover:
+ {incl_mods,[m1]}.</code>
+
+ <p>This would give an entry for <c>m1</c> also in the cover log
+ for the <c>s2</c> test run. The problem is that this would only
+ reflect the coverage by <c>s2</c> tests, not the accumulated
+ result over <c>s1</c> and <c>s2</c>. And this is where the cross
+ cover mechanism comes in handy.</p>
+
+ <p>If instead the cover specification for <c>s2</c> was like
+ this:</p>
+
+<code type="none">
+s2.cover:
+ {cross,[{s1,[m1]}]}.</code>
+
+ <p>then <c>m1</c> would be cover compiled in the <c>s2</c> test
+ run, but not shown in the coverage log. Instead, if
+ <c>ct_cover:cross_cover_analyse/2</c> is called after both
+ <c>s1</c> and <c>s2</c> test runs are completed, the accumulated
+ result for <c>m1</c> would be available in the cross cover log for
+ the <c>s1</c> test run.</p>
+
+ <p>The call to the analyse function must be like this:</p>
+
+<code type="none">
+ct_cover:cross_cover_analyse(Level, [{s1,S1LogDir},{s2,S2LogDir}]).</code>
+
+ <p>where <c>S1LogDir</c> and <c>S2LogDir</c> are the directories
+ named <c>&lt;TestName&gt;.logs</c> for each test respectively.</p>
+
+ <p>Note the tags <c>s1</c> and <c>s2</c> which are used in the
+ cover specification file and in the call to
+ <c>ct_cover:cross_cover_analyse/2</c>. The point of these are only
+ to map the modules specified in the cover specification to the log
+ directory specified in the call to the analyse function. The name
+ of the tag has no meaning beyond this.</p>

-%% The modules listed in the cross.cover file are modules that are

-%% to.
-%%
-%% For example, the lists module is listed in cross.cover to be
-%% included in all tests. lists belongs to the stdlib
-%% application. cross_cover_analyse/1 will create a file named
-%% cross_cover.html under the newest stdlib.logs/run.xxx directory,
-%% where the coverage result for the lists module from all tests is
-%% presented.
-%%
-%% The lists module is also presented in the normal coverage log
-%% for stdlib, but that only includes the coverage achieved by
-%% the stdlib tests themselves.
-%%
-%% The Cross cover file cross.cover contains elements like this:
-%% {App,Modules}.
-%% where App can be an application name or the atom all. The
-%% application (or all applications) shall cover compile the listed
-%% Modules.
+%% {cross,[{Tag,List}]} part of the App.cover file
+%%
+%% The modules listed in the 'cross' part of the cover file are
+%% modules that are heavily used by other tests than the one where
+%% they are explicitly tested. They should then be listed as 'cross'
+%% in the cover file for the test where they are used but do not
+%% belong.
+%%
+%% After all tests are completed, the these modules can be analysed
+%% with coverage data from all tests where they are compiled - see
+%% cross_cover_analyse/2. The result is stored in a file called
+%% cross_cover.html in the run.<timestamp> directory of the
+%% test the modules belong to.
+%%
+%% Example:
+%% If the module m1 belongs to system s1 but is heavily used also in
+%% the tests for another system s2, then the cover files for the two
+%% systems could be like this:
+%%
+%% s1.cover:
+%% {include,[m1]}.
+%%
+%% s2.cover:
+%% {include,[....]}. % modules belonging to system s2
+%% {cross,[{s1,[m1]}]}.
+%%
+%% When the tests for both s1 and s2 are completed, run
+%% cross_cover_analyse(Level,[{s1,S1LogDir},{s2,S2LogDir}]), and
+%% the accumulated cover data for m1 will be written to
+%% S1LogDir/[run.<timestamp>/]cross_cover.html
+%%
+%% S1LogDir and S2LogDir are either the run.<timestamp> directories
+%% for the two tests, or the parent directory of these, in which case
+%% the latest run.<timestamp> directory will be chosen.
+%%
+%% Note that the m1 module will also be presented in the normal
+%% coverage log for s1 (due to the include statement in s1.cover), but
+%% that only includes the coverage achieved by the s1 test itself.
+%%
+%% The Tag in the 'cross' statement in the cover file has no other
+%% purpose than mapping the list of modules ([m1] in the example
+%% above) to the correct log directory where it should be included in
+%% the cross_cover.html file (S1LogDir in the example above).
+%% I.e. the value of the Tag has no meaning, it could be foo as well
