multithreading - NSProgressIndicator built-in animation raises CA_ASSERT_MAIN_THREAD_TRANSACTIONS -


this looks bug in either nsprogressindicator or xcode 9 me:

  • run xcode 9 beta 1 or beta 4, in macos 10.12.6.
  • file > new project, macos, cocoa app, objective-c or swift, arc or not, no storyboards, latest (10.13) sdk.
  • in app target's environment, set ca_assert_main_thread_transactions=1.
  • in app delegate, add iboutlet progressindicator.
  • in nib, add nsprogressindicator window, connect outlet. leave checkbox indeterminate switched on.
  • in -applicationdidfinishlaunching, call -startanimation: on progressindicator.
  • build , run.

expected result:

progress indicator should happily show indeterminate progress, because did on main thread.

actual result:

app crashes, citing ca_assert_main_thread_transactions, when -startanimation: called.

you can see in tiny demo project.

did wrong? expected result incorrect?

p.s. asked on apple's developer forums, still awaiting moderator approval after 2 working days, deleted , came here instead :(

update: still lacking explanation, filed apple bug 33593575.

this bug in nsprogressindicator. bug report (thank filing!) marked duplicate of earlier bug, resolved in macos 10.13.

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
