Err thrown when multiple cy.server() in one file's before

[jennifer-shehane]

When I have a file that has multiple cy.server() in seperate parent-level describe's before, this error is thrown on second cy.server:

CypressError: The XHR server is unavailable or missing. This should never happen and likely is a bug. Open an issue if you see this message.

Example Code

describe "Model 1 [279]", ->
  before ->
    cy
      .visit("views/index.html")
      .server()

  it "foo bars [27a]", ->
    expect(true).to.be.true

describe "Model 2 [27b]", ->
  before ->
    cy
      .visit("views/index.html")
      .server()

  it "foo bars [27c]", ->
    expect(true).to.be.true

Fixed in 0.12.6.

The above behavior is now happening again in 0.19.2. I have not tracked down which version caused the regression.

The code for this is done, but this has yet to be released. We'll update this issue and reference the changelog when it's released.

Did some debugging, here's some combinations which work (so you can hack around it in the meantime):

this works>
-describe
	-describe
		-before(() => cy.server())
		-it - works fine!
		-describe
			-it - works fine!
-describe
	-describe
		-before(() => cy.server())
		-it - works fine
		-describe
			-it - works fine!

this works too>
describe
	-describe
		-describe
			-before(() => cy.server())
			-it - works fine!
			-describe
				-it - works fine!
	-describe
		-describe
			-before(() => cy.server())
			-it - works fine
			-describe
				-it - works fine!

Some of the not working ones:

this doesn't work>
-describe
	-before(() => cy.server())
	-it - works fine!
	-describe
		-it - works fine!
-describe
	-before(() => cy.server())
	-it - :((((
	-describe
		-it - :((((

this doesn't work>
-describe
	-it (with cy.server()) - this works!
	-describe
		-before(() => cy.server()) - :((((
		-it - ignored because .before() fails :/
		-describe
			-it - ignored because .before() fails :/
