-    // Specify Test Files
-    // ==================
-    // Define which test specs should run. The pattern is relative to the directory
-    // from which `wdio` was called. Notice that, if you are calling `wdio` from an
-    // NPM script (see https://docs.npmjs.com/cli/run-script) then the current working
-    // directory is where your package.json resides, so `wdio` will be called from there.

-    // ============
-    // Capabilities
-    // ============
-    // Define your capabilities here. WebdriverIO can run multiple capabilities at the same
-    // time. Depending on the number of capabilities, WebdriverIO launches several test
-    // sessions. Within your capabilities you can overwrite the spec and exclude options in
-    // order to group specific specs to a specific capability.
-    //
-    // First, you can define how many instances should be started at the same time. Let's
-    // say you have 3 different capabilities (Chrome, Firefox, and Safari) and you have
-    // set maxInstances to 1; wdio will spawn 3 processes. Therefore, if you have 10 spec
-    // files and you set maxInstances to 10, all spec files will get tested at the same time
-    // and 30 processes will get spawned. The property handles how many capabilities
-    // from the same test should run tests.
-    //
-    maxInstances: 10,

-    // If you have trouble getting all important capabilities together, check out the
