ruby - Simplifying rspec unit tests -

-

There is a lot of cumbersome and unnecessary in unit testing in the RSPC for specifying both a reference and a kiss. For example: 

  reference 'type =: invalid' do (: type) {: invalid} this {hope} {subject}. Raise_error (ArgumentError)} End

If I can do something like this then it would be nice (Overall in many trials): 

  let_context Type: : Invalidate {hope {subject}. The rule will define a reference and the argument for more reference to me such as  type =: invalid  or  Let's (: type) {: invalid}  Because I have nothing else to say that this variable has been changed.

Edit: In the socket: The CanReceive () argument was the reason I was checking the input 1 millisecond While stepping into GDB, everything worked out. I have a problem with C sock send () / recv () do nothing if they are in non-debug mode. Even if std :: cout can not return their return value for some reason std :: cout is not working in my method I std: : Cerr can not even make a mistake It does not make sense to check that in GDB, because everything works perfectly as a virus in non-debug mode. C does not. //b - buffer // s - size // sd - socket descriptor int32_t TCP :: reception (char * b, uint32_t s) {error :: critical. SetErrorNumber (error: List :: noor); If (!

GO: Serve static pages -

I'm trying to display a static page with Go. Go: Package main import "net / http" function main () {fs: = http.FileServer (http.Dir ("static / house")) Http: .handle ("/", fs) http.ListenAndServe (": 4747", zero)} directory: project / stable home Html edit.html project.go When I run it, the web page displays links to edit.html and home.html instead of displaying a static page from home.html is. What am I doing wrong. Is this the best way to serve files? I know that there are other ways like From the HTML / templates package, but I'm not sure what is the difference between each of these methods and when. Thanks! fancy main () {http.Handle ("/", http.FileServer (Http) .ir ("static")) http.ListenAndServe (": 4747", zero)} You do not need static / home , just Static . and when you do not have index.html in / static , the directory instead Content appears. Just change the name of...

I want to use the front and rear camera at the same time in iOS development: when I take a photo back After the camera, the front camera can be opened and another can take a photo.
