ios - Xcode UITesting: label disappears from hierarchy and won't come back -

-

this using xcode 7.2.1 , swift 2.0.

i have table cell containing uilabel used display error message. @ initial load blanked using code this:

cell.errorlabel.alpha = 0.0 cell.errorlabel.text = nil

then later on when i've detected error want display this:

cell.label.text = "to" cell.errorlabel.alpha = 1.0 cell.errorlabel.text = "error !!!!"

this works fine when running app. when running in ui test, try test error being displayed this:

let tocell = xcuiapplication().tables.... // finds cell label 'to' xctasserttrue(tocell.statictexts["error !!!!"].exists)

and fails. i've verified i'm getting right cell checking other ('to') label present. is. ui testing not see error label. i've tested adding break point , using debugger this:

(lldb) p tocell.statictexts.count     t =   427.03s     number of matches for: descendants matching type statictext     t =   427.29s         snapshot accessibility hierarchy enterprise.com.me     t =   427.31s         find: descendants matching type table (uint) $r2 = 1     t =   427.31s         find: descendants matching type cell     t =   427.32s         find: elements containing elements matching type statictext identifier 'to'     t =   427.32s         find: descendants matching type statictext

the (uint) $r2 = 1 indicating there 1 static text present. looking @ simulator can see 2 uilabels.

i've tried number of things individually isolate issue - using alpha or setting text nil, or using uiview's hidden property. using of these options hide label renders invisible ui tests when later made visible, no matter try.

i'm quite confused , suspect it's bug. have ideas how ui tests see uilabel once make visible?

p.s. i've tried using wait loop wait label appear (using expectationforpredicate(...), uilabel has not shown up.

problem turned out had not set accessibilityelements property on cells. therefore accessibility having issues trying figure out in each one.

so if building custom cells table view, ensure set accessibilityelements property testing can find contents of cells.

Sass watch command compiles .scss files before full sftp upload -

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
