Specify Path of Chrome To Run?

[ebebbington]

Summary

What:

Not enitely sure how this would be done, or if it can be, but i think it'll be good to specify what chrome version to use (and at a later point, which other browser versions to use when more are supported)

Why:

When you're running browser tests, the browser version is key - something might break or might not work on one version, but work on another. For example, if i have a prod app, i might want to tell it on the following browsers:

• Chrom v68
• Chrome latest
• Chrome v67 (maybe i want to support users using this version, so i wanna make sure everything works here too)

Acceptance Criteria

Below is a list of tasks that must be completed before this issue can be closed.

• Write documentation
• Write unit tests
• Write integration tests
• Da feature

Example Pseudo Code (for implementation)

Don't think it's possible, in the sense of being able to do const Sinco = new HeadlessBrowser({ version: 68 }) because the chrome. browser points to the users installation

But maybe we could allow a path for the config, eg from a users perspective:

$ alias chome_v68="/Users/.../chrome.68.exe" # or export CHROME_V68="..."
$ cat app_test.ts

const Sinco = new HeadlessBrowser({ path: "chrome_v68" }) # or path: "$CHROME_V68"

Internally, the above would look like:

constructor (configs) {
  this.path = configs.path
}
public start () {
  Deno.run({
    cmd: [..., this.configs.path]
  })
}
