Running script locally

1. Add this to the top of your script, the library mimcs the Synthetics API and implements most common commands in Synthetics.

It's important that global._isApiTest is set to false, for scripted browser tests.

    if (typeof $env === "undefined" || $env === null) {
      global._isApiTest = true;  // false, for Scripted Browser
      require("../lib/simulator");
    }

2. Execute the script by hitting F5 from VScode or open a terminal, run node <filename>.js in the ./monitors directory.

monitors>  node <filename>.js

TypeError: $browser.get is not a function. When running scripted browsers.

Make sure that you've set: global._isApiTest = false

Can't find Node.js binary "node": path does not exist. Make sure Node.js is installed and in your PATH, or set the "runtimeExecutable" in your launch.json

Edit the file .vscode/launch.json , and add the "runtimeExecutable" property with the Node path:

      "runtimeExecutable": "<Node binary absolute path>",

Example:

  {
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Launch Program",
      "skipFiles": ["<node_internals>/**"],
      "runtimeExecutable": "/Users/btan/.nvm/versions/node/v12.13.0/bin/node",
      "program": "${file}"
    }
  ]
