javascript - Blanket.js vs Istanbul-js vs JSCover -

-

i trying decide on js test code coverage tool cannot see differences between them. top hits in google blanket.js, istanbul-js , jscover.

can offer information on key differences between them , advantages/disadvantages?

are there other useful ones out there?

after trying around find istanbul convenient tool bring coverage analysis node-js project.

  • its installed npm install
  • it sets behavior via .istanbul.yml
  • gets invoked own executable
  • it provides multiple report formats such clover, lcov, jscoverage, etc.

istanbul uses provided executable or js-script perform tests , collect coverage information. can installed via npm:

npm install istanbul mocha

after successful installation invoke 

./node_modules/.bin/istanbul cover ./node_modules/.bin/_mocha

respect '_' since mocha forks _mocha-executable stated here

blanket.js nodejs integrates

  • its installed npm install
  • configuring behavior via package.json
  • getting invoked mocha requiring blanket @ commandline
  • generating statistics interpreted mocha's reporters, i.e. html-cov
  • can used in browser js

basically ready use after doing

npm install blanket mocha

after successful installation run mocha tests that

./node_modules/.bin/mocha --require blanket --reporter html-cov >coverage.html

unfortunately have invoke mocha tests twice if want collect coverage information collect test reports since can provide 1 reporter mocha.

i can not jscover since installation complicated me. important me not have install packages root or compile things since becomes more complicated other users create development environment.

in program creating in python/pygame, screen.blit not working. in other programs have made, screen.blit works. error: traceback (most recent call last): file "c:...\main.py", line 46, in <module> screen.blit(sight.image, sight.rect) attributeerror: 'int' object has no attribute 'blit' the error in question caused screen variable being allocated integer instead of pygame.surface() object.perhaps accidentally rewrote variable somewhere? from can make of doing, seems stating position of blit full rect instead of coordinate. when do: screen.blit(sight.image,sight.rect) what program seeing is: screen.blit(sight.image,(sight.rect.x,sight.rect.y,sight.rect.width,sight.rect.height)) i assuming don't intend this. remember rect object consists of position, width , height. to correct code, put (sight.rect.x,sight.rect.y) location goes instead this: screen.blit(sight.image,(sight.rect.x,sight.rect.y)) the .x , .y corres
