Testing and Development Tools and Tips

This is a collection of helpful tools and tips for navigating the OpenSSL code base and managing a local git repository.

Testing Environment and Tools

In the test-util branch of Mike Bland's fork are a few helper files that you may wish to copy or pull into your branch.

test/testutil.h

Defines the generic SETUP_TEST_FIXTURE and EXECUTE_TEST macros. Should be pulled into the mainline pending acceptance of pull request #126.

test/new-test.sh

Generates a new automated test stub, following the Pseudo-xUnit Pattern and using the macros from test/testutil.h. The generated stub will compile standalone.

test/test_env.bash

Environment variables, functions, and aliases to help with OpenSSL unit testing. The header comments contain documentation on each of the functions and aliases in the file.

Cscope

Cscope is a powerful C source code browser. Once you have it installed, you can use the make-cscope and open-cscope functions from test/test_env.bash.

Vim Integration

Once $CSCOPE_DB (defined in test/test_env.bash is built using make-cscope, you can take advantage of the Cscope integration in Vim by adding something like the following to your .vimrc:

" Detect whether cscope features are present and whether we should add a
" connection to an existing cscope.out database file
if has("cscope")
  set nocsverb
  if filereadable("./cscope.out")
    cs add cscope.out
  elseif $CSCOPE_DB != ""
    if filereadable($CSCOPE_DB)
      cs add $CSCOPE_DB
    else
      echo "Can't read $CSCOPE_DB; cscope add not run"
    endif
  endif
  set csre
  set csverb
endif

Ctags

Ctags generates an index of symbols that many editors can use to quickly navigate the source code. Though many Unices ship with a version installed at /usr/bin/ctags, test_env.bash presumes that Exuberant Ctags is installed.

Vim Integration

Add this to your .vimrc to take advantage of Ctags integration in vim:

" The tags path, as set below, will search the local file first, then the       
" project-wide file.
if $TAGS_FILE != ""                                                             
  if filereadable($TAGS_FILE)
    set tags+=$TAGS_FILE
  else                                                                          
    echo "Can't read $TAGS_FILE; tags not set"
  endif
endif
