<div>This could be fixed in cover by taking the compile options from the beam file as you assumed how it works.</div><div><br></div><div>Actually the documentation still says that "Only options defining include file directories and
macros are passed to <span>compile:file/2</span>, everything else is

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">It seems that there is no way to cover-compile modules with export_all.<br>
Here is a simple example:<br>
<br>
cover_test.erl:<br>
<br>
-module(cover_test).<br>
test() -> ok.<br>
<br>
<br>
$ erl<br>
Erlang R15B01 (erts-5.9.1) [source] [64-bit] [smp:4:4]<br>
[async-threads:0] [hipe] [kernel-poll:false]<br>
<br>
Eshell V5.9.1 (abort with ^G)<br>
1> c(cover_test, [debug_info,export_all]).<br>
{ok,cover_test}<br>
2> cover_test:test().<br>
ok<br>
3> cover:compile_beam(cover_test).<br>
{ok,cover_test}<br>
4> cover_test:test().<br>
** exception error: undefined function cover_test:test/0<br>
5><br>
<br>
<br>
Could someone explain why it is like this? Is it done on purpose?<br>
Maybe it's a bug?<br>
The reason I want modules to be cover-compiled with +export_all is<br>
that it is sometimes convinient to have unit tests outside of a<br>
module. Before unit tests are run the modules get compiled with<br>
+export_all for tests to be able to access private functions. But the<br>
situation is that it is not possibe in this case to enable coverage<br>
analysys.<br>
