istanbul cover: more than one command ?

[rundef]

Hi, I have a projects who has two test frameworks :

• Cucumber for BDD tests
• Mocha for unit tests

We're trying to use istanbul to calculate code coverage, but we aren't able to calculate both the unit tests coverage and bdd tests coverage at the same time.

istanbul cover ./node_modules/.bin/mocha works istanbul cover ./node_modules/.bin/cucumberjs works istanbul cover ./node_modules/.bin/mocha ./node_modules/.bin/cucumberjs doesn't work

From what I understand, the ./node_modules/.bin/cucumberjs part is sent as command line argument to mocha.

Is there any way to make this work ?

Thanks

What I normally do is run the unit coverage and drop it into a ./unit directory and then run the bdd tests and drop them into ./bdd. Then use a script like this to generate the results for both:

var istanbul = require('istanbul'),
    path = require('path'),
    collector = new istanbul.Collector();

    ['unit', 'bdd'].forEach(function(item) {
        var file = path.join(__dirname, item, 'coverage.json');
        collector.add(JSON.parse(fs.readFileSync(file, 'utf8')));
    });

    ['lcov', 'json'].forEach(function(type) {
        var report = istanbul.Report.create(type, {
            dir: path.join(__dirname, 'full')
        });
        report.writeReport(collector, true);
    });

Works perfectly, thank you @davglass
