python - PyCharm - Trailing type hints and line width limit -


in pycharm, typically use trailing type hints (not sure of right way of calling them) variables such this:

my_var = my_other_variable  # type: myobject

however, have long line cannot split, or type hint bit long, such as:

my_var = my_really_long_variable_name  # type: qtwidgets.qverylongqtclassname

this make full line longer line width limit (79 characters), , hence pycharm flag warning.

hence, is there way put type hint in different line? tried these not seem work:

# type: qtwidgets.qverylongqtclassname my_var = my_really_long_variable_name  my_var = my_really_long_variable_name \     # type: qtwidgets.qverylongqtclassname

the closest thing can think of this, may not shorten line width:

my_var = \     my_really_long_variable_name  # type: qtwidgets.qverylongqtclassname

otherwise, alternative have this:

v = my_really_long_variable_name my_var = v  # type: qtwidgets.qverylongqtclassname

the other alternative of shortening type not seem work based on tests have done; pycharm seems struggle recognising my_var's type qtwidgets.qverylongqtclassname in case:

t = qtwidgets.qverylongqtclassname my_var = my_really_long_variable_name  # type: t

i found convenient import class names directly module type annotation usage. example:

from qtwidgets import qverylongqtclassname my_var = my_really_long_variable_name  # type: qverylongqtclassname

i have not encountered problem yours yet attitude.

however, found version readable , convenient way annotate long line:

my_var = \     my_really_long_variable_name  # type: qtwidgets.qverylongqtclassname

update: way implement this:

my_var = (     my_really_long_variable_name )  # type: qtwidgets.qverylongqtclassname

in addition, supported , not cause problems in ides.

vue.js - Create hooks for automated testing -

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
