Webdriver.io test runner - exclude suite from specific capability - selenium

Question

My webdriver.io test runner is organized into suites, and I want to exclude a suite from a specific capability.
For example, I have a suite called suite1:
//
suites: {
suite1: [
'./test/spec/*.js',
],
},
//
And I want to exclude this suite from the Safari capability:
//
{
'tunnelIdentifier' : sltunnel,
'browserName': 'safari',
'version': '10',
'platform': 'OS X 10.12',
'screenResolution': '1600x1200',
'exclude': [
suite1,
],
},
//
Is there a way to achieve this?

Answer 1

Of course there are multiple ways to do this, but at the end of the day it's all up to you.
You can drag your entire suite logic outside of your wdio.conf.js file into a separate config file (I'm sure you might already have one for your environments: test, prod, w/e) and then import it (via require into your wdio.conf.js file):
So let's say you have suites.conf.js file:
module.exports.suites = {
// 1 => run the suite
// 0 => don't run it
"chrome": {
"0": [
"<yourSuiteName-001>.js"
"<yourSuiteName-003>.js"
"<yourSuiteName-005>.js"
],
"1": [
"<yourSuiteName-002>.js"
"<yourSuiteName-004>.js"
]
},
"safari" : {
"0": [
"<yourSuiteName-002>.js"
"<yourSuiteName-004>.js"
"<yourSuiteName-005>.js"
],
"1": [
"<yourSuiteName-001>.js"
"<yourSuiteName-003>.js"
]
}
// <etc>
}
Then you import it into your wdio.conf.js file (var suites = require(./<pathToSuitesConfig>/suites.conf.js);), cycle with a forEach through all your suites and based on your browserName, create a buffer in which you store the runable suites as they match your condition, then add them into the config file. This logic will go in your wdio.conf.js header section and you can update the exportable config via the results.
I just thought of this in like 5 minutes, so I'm sure there's multiple cleaner ways to achieve this.
Alternatively, you can look at other test-runners that are easy to plug into WebdriverIO and which have tagging:
Cucumber has a great tagging mechanism (due to Gherkin syntax);
Mocha has something similar called, you guessed it tagging.
