javascript - How to ensure DRY code in Jasmine Unit tests? -


if have popover say, , want test it:

  1. being created
  2. being manipulated
  3. being destroyed

it beneficial have declared in 1 place (tucked inside "describe"), can shared across "its".

should 1 share things between tests? i.e test2 relies on test1 being run first? best way jasmine?

it`s bad thing rely test order. share things between tests can have way set state of object. assume pseudo code below:

var popover = getpopover({state:'init'}); //checking init state ... //other test starting var popover = getpopover({state:'manipulated'}); //checking state

so main idea able init object @ state need. note, if it's not code perform initialization , not going need reuse much, can hardcode state setup every test. sure, it's not dry, benefit tests can read, without references other methods. sometime it's thing, depends.

also, can use beforeeach , aftereach setup , teardown before , after every test( it's describe level thing ). 1 of preferred ways perform state initialization , cleanup.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
