How to run a single test in nightwatch
For me, it only works with:
npm run test -- tests/01_login.js --testcase "Should login into Dashboard"
npm run <script> -- <test suite path> --testcase "<test case>"
my script in package.json:
"test": "env-cmd -f ./.env nightwatch --retries 2 --env selenium.chrome",
at nightwatch version 1.3.4
You can also use tags:
npm run <script> -- <enviroment> <tag>
npm run test -- --env chrome --tag login
just add it to your test case:
module.exports = {
'@tags': ['login', 'sanity', 'zero1'],
...
}
You must use specific tags before function and separate all functions in diferent files under tests directory, and then call command with --tag argument. See wiki nightwatch tags page and watch this example:
// --- file1.js ---
module.exports = {
tags: ['login'],
'Test 1':function(){
//TODO test 1
}
};
// --- file2.js ---
module.exports = {
tags: ['special', 'createUser'],
'Test 2':function(){
//TODO test 2
},
};
// --- file3.js ---
module.exports = {
tags: ['logoff', 'special'],
'Test 3':function(){
//TODO test 3
},
}
If you run:
nightwatch.js --tag login
only runs Test 1, however if you run:
nightwatch.js --tag special
Test 2 and Test 3 will be executed.
You can specific more than one tag
nightwatch.js --tag tag1 --tag tag2
Separate each test function is mandatory because Nightwatch handled with filematcher each file. See Github code.
PD: If file has syntax errors, is possible that test don't run or test hasn't been found
The --testcase flag can since version 0.6 be used to run a single test from the commandline, e.g.
nightwatch.js --test tests\demo.js --testcase "Test 1"
This could be done using either test groups or test tags. You can also execute a single test with the --test
flag, e.g.
nightwatch.js --test tests\demo.js
A new parameter --testcase has been added to run a specified testcase.
nightwatch.js --test tests\demo.js --testcase "Test 1"
It's a new feature since the v0.6.0
