language agnostic - Guidelines for better unit tests -

-

Jimmy Bogard, an article is written, where it gives four rules:

  • < Strong> Test names from the user's perspective
  • Tests are codes too, give them some love
  • don
  • One setup , execute and verify

in your opinion are these guidelines fulfilled? What are your guidelines for unit tests? Please avoid specific language idioms, try to keep the answer-language agnostic.

A complete, 850 page book is called this deal with this topic, so there is nothing like this Which can be easily boiled for some strict rules (although the rules of your mentions are good).

Another digestible book that covers this topic

If I can add rules I Most are important, then they will be:

  • Use test-induced development This is the most effective road towards good unit tests. It is most difficult to try to withdraw unit tests in the existing code.
  • Keep it simple: Ideally, a unit test should be less than 10 lines of code. If it grows for more than 20 lines, then you should seriously consider the test code or the refactoring API you are testing.
  • Keep It Fast It is meant to execute unit test suites very often, so aiming to keep the entire association under 10 S. It can easily mean that keeping each test under 10 ms needed.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
