问题
Backend of our app is in PHP
and for frontend we are using AngularJs
.
We successfully managed to run e2e tests on local as well as on production server using protractor
.
After writing loads of e2e tests for our app, we started looking for its coverage similar to that of unit testing. After searching for lot, luckily we find https://www.npmjs.com/package/grunt-protractor-coverage , exactly what we wanted.
I took help from http://lkrnac.net/blog/2014/04/measuring-code-coverage-by-protractor/ article which beautifully helps in setting up everything. I setup the config and other grunt tasks for my app, and finally our code(js files) were properly instrumented. I copied the rest of the files(html, static, etc.) to that instrumented code and provided the correct path for the proractor-config
file. Tests started running as they were running before, but this time with instrumented files.
Till this point, everything is OK
. But when the task for generating coverage-report
was executed, we figured that we had empty coverage.json
file {}
. This means the report will surely be empty as it reads that file to generate report, and as far as I have figured out, this file is generated by protractor-coverage
grunt task while tests are executing. It sends the information to the collector(port: 3001
) using a POST
req and while generating report, a GET
req is being made to the same collector.
So, what I figured is, No POST
req is being made to collector.
var options = {
hostname: 'localhost',
port: <%=collectorPort%>,
path: '/data',
method: 'POST',
headers:{
'Content-Type':'application/json'
}
};
function saveCoverage(data){
var req = http.request(options, function(res) {
res.on('data', function (chunk) {
});
});
req.on('error', function(e) {
console.log('problem with request: ' + e.message);
});
// write data to request body
req.write(JSON.stringify(data));
req.write('\n');
req.end();
}
Each time it just shows
where it should have listed down every file:And also, that 100
everywhere is misleading, I ran tests for the source code: http://lkrnac.net/blog/2014/04/measuring-code-coverage-by-protractor/ as explained, but even if there's only one e2e test, the report must have given the actual numbers instead of giving a straight 100
for all.
It might happen that I have some wrong configuration or missed something.
Below are my files:
'use strict';
module.exports = function(grunt) {
// Load grunt tasks automatically
require('load-grunt-tasks')(grunt);
// Define the configuration for all the tasks
grunt.initConfig({
// Project settings
yeoman: {
// configurable paths
app: 'app',
dist: 'dist-test',
e2e: 'coverage/e2e',
instrumentedServer: 'coverage/server/instrument',
instrumentedE2E: 'coverage/e2e/instrumented'
},
// Empties folders to start fresh
clean: {
coverageE2E: {
src: ['<%= yeoman.e2e %>/'],
}
},
// Copies remaining files to places other tasks can use
copy: {
coverageE2E: {
files: [{
expand: true,
dot: true,
cwd: '<%= yeoman.app %>',
dest: '<%= yeoman.e2e %>/instrumented/app',
src: [
'**/*',
'!modules/**/*.js',
'!editor/**/*.js'
]
}, {
expand: true,
cwd: '.tmp/images',
dest: '<%= yeoman.e2e %>/instrumented/app/images',
src: ['generated/*']
}, ]
},
},
// start - code coverage settings
instrument: {
files: ['app/modules/**/*.js', 'app/editor/**/*.js'],
options: {
lazy: true,
basePath: 'coverage/e2e/instrumented/'
}
},
makeReport: {
src: '<%= yeoman.instrumentedE2E %>/*.json',
options: {
type: 'html',
dir: '<%= yeoman.e2e %>/reports',
print: 'detail',
// type: 'lcov'
// dir: 'reports'
}
},
protractor_coverage: {
options: {
configFile: 'test/e2e/protractor-config.js', // Default config file
keepAlive: true, // If false, the grunt process stops when the test fails.
noColor: false, // If true, protractor will not use colors in its output.
coverageDir: '<%= yeoman.instrumentedE2E %>',
args: {},
run: {}
},
chrome: {
options: {
args: {
baseUrl: 'https://localapp.vwo.com/v3/#/',
// Arguments passed to the command
'browser': 'chrome'
}
}
}
}
});
grunt.registerTask('default', [
'clean:coverageE2E',
'copy:coverageE2E',
'instrument',
'protractor_coverage:chrome',
'makeReport'
]);
};
And my coverage.json
file:
{}
