Protractor Pause On Failure

Question

I am new to protractor and I am trying to figure out how to make the test/runner pause on failure. Ideally I would love to transition to the nodejs debugger but am open to any suggestion.

My use case is basically, when a test fails I would like to see what state the UI is in to help understand why the test failed.

You can also add to the jasmine config, to stop when spec fails: (same as how protractor-screenshot-reporter works)

for jasmine 1:

onPrepare: function () {
    exports.config = {
        onPrepare: function () {
            jasmine.getEnv().addReporter({
                reportSpecResults: function (spec) {
                    if (!spec.results().passed()) {
                        spec.results().items_.forEach(function (v) {
                            console.log(v.trace.stack);
                        });
                        browser.pause();
                    }
                }
            });
        }
    }
}

for jasmine2:

onPrepare: function () {
    jasmine.getEnv().addReporter({
        specDone: function (spec) {
            if (spec.status === 'failed') {
                console.dir(spec.failedExpectations.length);
                console.log(spec.failedExpectations[0].message);
                console.log(spec.failedExpectations[0].stack);
                browser.pause();
            }
        }
    });
}

then by typing "repl" in the console you switch to interactive mode, so you can try out the protractor commands.

You can put browser to sleep after or before your expect line to see what's going on.

browser.sleep(20000); // sleep 20 seconds

Update:

protractor now supports .pause() method.

browser.pause()
