npm install did_it_work
var process = require('did_it_work');
process('my_awesome_program')
.goodIfMatches(/Ready/, 1000)
.badIfMatches(/Error/)
.good(function(){
console.log('The program worked (because it spat out "Ready" to stdout within 1000ms).')
})
.bad(function(){
console.log('The program didn\'t work (because it spat out "Error" to stdout, or the program exited with non-zero code, or it didn\'t spit out "Ready" within 1000ms)')
})
.complete(function(){
console.log('In any case, the program exited')
})
spawn
instead of exec
If you pass one string argument to the function, it will use child_process.exec
to create the process. If, on the other hand, you need to use child_process.spawn
, pass two arguments instead, the first being the executable and the second being an array of arguments. Example
process('echo', ['hello', 'world'])
.complete(function(stdout){
console.log('The program returned ' + stdout)
})
