    // ==================
    // Specify Test Files
    // ==================
    // Define which test specs should run. The pattern is relative to the directory
    // of the configuration file being run.
    //
    // The specs are defined as an array of spec files (optionally using wildcards
    // that will be expanded). The test for each spec file will be run in a separate
    // worker process. In order to have a group of spec files run in the same worker
    // process simply enclose them in an array within the specs array.
    //
    // The path of the spec files will be resolved relative from the directory of
    // of the config file unless it's absolute.
    //
    specs: [
        './features/**/*.feature'
    ],
    // Patterns to exclude.
    exclude: [
        // 'path/to/excluded/files'
    ],
    //
    // ============
    // 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
    // Sauce Labs platform configurator - a great tool to configure your capabilities:
    // https://saucelabs.com/platform/platform-configurator
    //

        browserName: 'chrome'

    // methods to it. If one of them returns with a promise, WebdriverIO will wait until that promise got
    // resolved to continue.
