unit testing - mock out return of a method base on the number of invocation only in spock -

-

Is it possible to copy the return value of a method based on NT time? Note that I do not want to specify passed parameters because it does not matter for a specific test case. For example, for the first call it should be returned, it should be returned for the second call.

Yes it is possible. 

  someObject.someMethod (* _) & Gt; & Gt; & Gt; ['X', 'Y']

This will return to the second invitation of the method on x and y .

example: 

  zero "test something" () {given: def sample = duplicate (sample) {some method (_) & gt; & Gt; & Gt; ['Hello', 'world']} Hopefully: sample.someMethod ('foo') == 'Hello' sample. Some method ('bar') == 'world'} Sample of class {def someMethod (Df A ) {Return A}}

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
