python - Behave / python3: Test undefined even if the step function is present -


i have started using behave define behaviour-driven tests on python3. first tests went fine, incurring in puzzling error.

i have define gherkin file sra-to-isatab-batch-conversion.feature:

feature: sra isa-tab batch conversion # perform batch conversion of set of sra datasets, retrieved european nucleotide archive # isa-tab  scenario: batch conversion form list of sra accession numbers  given access number "era000084"  , nothing else  when sra isa tab conversion invoked  should return zip file object  , zip file should contain many directories element in list

then define following step methods in file steps/sra-to-isatab-batch-conversion.py

from behave import *  use_step_matcher("parse")   @given('an access number "{access_number}"') def step_impl(context, access_number):     context.access_number = access_number     print(context.access_number)  @step("nothing else") def step_impl(context):     print("nothing else")    @when("the sra isa tab conversion invoked") def step_impl(context):  pass   @then("it should return zip file object") def step_impl(context):     pass   @step("the zip file should contain many directories element in list") def step_impl(context):     pass

if run behave sra-to-isatab-conversion.feature step function related when step appears missing:

feature: sra isa-tab batch conversion # sra-to-isatab-batch-conversion.feature:2  scenario: batch conversion form list of sra accession numbers                  # sra-to-isatab-batch-conversion.feature:6 given access number "era000084"                                             # steps/sra-to-isatab-batch-conversion.py:6 0.000s , nothing else                                                               # steps/sra-to-isatab-batch-conversion.py:40 0.000s when sra isa tab conversion invoked                                  # none should return zip file object                                        # none , zip file should contain many directories element in list # none  /users/massi/projects/oerc/isa-api/features/test_outputs  failing scenarios:   sra-to-isatab-batch-conversion.feature:6  batch conversion form list of sra accession numbers  0 features passed, 1 failed, 0 skipped 0 scenarios passed, 1 failed, 0 skipped 2 steps passed, 0 failed, 2 skipped, 1 undefined took 0m0.001s  can implement step definitions undefined steps these snippets:  @when(u'the sra isa tab conversion invoked') def step_impl(context):     raise notimplementederror(u'step: when sra isa tab conversion invoked')`

i have tried redefine step description change number of given statements,i have rewritten files, same errors. if copy statement suggested in error message still same error.

can explain me doing wrong? using python 3.4 behave 1.2.5 pycharm 5.0.4 (notice pycharm bdd tools recognise matching between statements in gherkin file , step functions)

hmmm, working fine me exact implementation pasted above. environment issue or , installation problem. can try reinstalling behave? running terminal or pycharm?

ps: not issue, don't need specify use_step_matcher() method if using parse; since default step_matcher

also (making sure not pasting human error you): @when step method has indentation issue on "pass" statement. in code or format issue here in forum?

caching - How to check if a url path exists in the service worker cache -

i need check if particular url path exists in service worker cache. example, suppose url is: /myserviceworker/service?a=110&b=70 this url exists in cache, there many of them different values of , b. now, suppose want refresh of these urls, how can that? i want know how access key values service worker cache. if know key, plan follows: var url = new url(key); if(url.pathname === "\/myserviceworker/service") refetch key but not sure how cache key , in format is. mean, string or url? cache api has match() method returns promise resolving in response object if match or undefined if no match exists. second parameter object can specify ignoresearch not take account url parameters. the ignoresearch option supported firefox ( chrome status here ). in other hand, retrieve cache entries, can use keys() method.

Redirect to a HTTPS version using .htaccess -

i need modify .htaccess file redirect urls https version without "www". http://example.com --> https://example.com http://www.example.com --> https://example.com https://www.example.com --> https://example.com this how .htaccess file looks like: rewriteengine on rewritecond %{request_filename} !-d rewritecond %{request_filename} !-f rewriterule ^(.*)$ redirect.php?id=$1&page=$2 [qsa,l] what modifications need make .htaccess in order forward https without "www"? it depends on doing current code. looks file called redirect trying display php page seo friendly url. think might confusing people. anyway, need , force https without www, need 1 more rule above. also second rule needs two capture groups in rewriterule test string because wanting 2 different values using $1 , $2 references. rewriteengine on #rediect www non www and/or http https --- combinations. rewritecond %{http_host} !^example\.com [nc,or] rewritecond %{https} !^
