pytest-cov 1.1

pytest-cov is a plugin that supports pytest's distributed testing feature in both load and each modes. Of course it also support centralised testing.<br /><br />It supports pretty much all features offered by the coverage package.<br /><br />Each test run with coverage activated may produce any combination of the four report types. There is the terminal report output by pytest, annotated source code, HTML and XML reports.<br /><br />#md5=1c09cb7d7e8f2042984911f7c19419c5<br /><br />Installation<br /><br />This plugin depends on features just added to py and pytest-xdist. Until py 1.2.2 and pytest-xdist 1.2 are released you will need to install the 'tip' development versions from:<br /><br />http://bitbucket.org/hpk42/py-trunk/downloads/<br /><br />http://bitbucket.org/hpk42/pytest-xdist/downloads/<br /><br />Usage<br /><br />Running centralised testing:<br /><br />py.test --cov myproj tests/<br /><br />Shows a terminal report:<br /><br />-------------------- coverage: platform linux2, python 2.6.4-final-0 ---------------------<br />Name Stmts Exec Cover Missing<br />--------------------------------------------------<br />myproj/__init__ 2 2 100%<br />myproj/myproj 257 244 94% 24-26, 99, 149, 233-236, 297-298, 369-370<br />myproj/feature4286 94 87 92% 183-188, 197<br />--------------------------------------------------<br />TOTAL 353 333 94%<br /><br />Distributed testing with dist mode set to load and branch coverage enabled:<br /><br />py.test -n 2 --cov myproj --cov-branch tests/<br /><br />The results from the slaves will be combined like so:<br /><br />-------------------- coverage: platform linux2, python 2.6.4-final-0 ---------------------<br />Name Stmts Exec Branch BrExec Cover Missing<br />----------------------------------------------------------------<br />myproj/__init__ 2 2 0 0 100%<br />myproj/myproj 257 244 56 50 93% 24-26, 99, 149, 233-236, 297-298, 369-370<br />myproj/feature4286 94 87 18 13 89% 183-188, 197<br />----------------------------------------------------------------<br />TOTAL 353 333 74 63 92%<br /><br />Distributed testing in each mode:<br /><br />py.test --cov myproj --dist=each<br /> --tx=popen//python=/usr/local/python264/bin/python<br /> --tx=popen//python=/usr/local/python265/bin/python<br /> tests/<br /><br />Will produce a report for each slave:<br /><br />-------------------- coverage: platform linux2, python 2.6.4-final-0 ---------------------<br />Name Stmts Exec Cover Missing<br />--------------------------------------------------<br />myproj/__init__ 2 2 100%<br />myproj/myproj 257 244 94% 24-26, 99, 149, 233-236, 297-298, 369-370<br />myproj/feature4286 94 87 92% 183-188, 197<br />--------------------------------------------------<br />TOTAL 353 333 94%<br />-------------------- coverage: platform linux2, python 2.6.5-final-0 ---------------------<br />Name Stmts Exec Cover Missing<br />--------------------------------------------------<br />myproj/__init__ 2 2 100%<br />myproj/myproj 257 244 94% 24-26, 99, 149, 233-236, 297-298, 369-370<br />myproj/feature4286 94 87 92% 183-188, 197<br />--------------------------------------------------<br />TOTAL 353 333 94%<br /><br />If desired distributed testing in each mode can instead produce a single combined report:<br /><br />py.test --cov myproj --cov-combine-each --dist=each<br /> --tx=popen//python=/usr/local/python264/bin/python<br /> --tx=popen//python=/usr/local/python265/bin/python<br /> tests/<br /><br />Which looks like:<br /><br />---------------------------------------- coverage ----------------------------------------<br /> platform linux2, python 2.6.4-final-0<br /> platform linux2, python 2.6.5-final-0<br />Name Stmts Exec Cover Missing<br />--------------------------------------------------<br />myproj/__init__ 2 2 100%<br />myproj/myproj 257 244 94% 24-26, 99, 149, 233-236, 297-298, 369-370<br />myproj/feature4286 94 87 92% 183-188, 197<br />--------------------------------------------------<br />TOTAL 353 333 94%<br /><br />#md5=28fb29184597f72cf3ca0e37009376f1
