Any way to alias fixture and also use in intercept (see examples)?

[Josh68]

Hello. This is an edge case question, but wondering if anyone has a pattern that could make it work.

I have multiple intercepts, which must be defined in order of specificity because of query params. Each one of them references a paramaterized fixture path. I also want to alias the fixtures for reference in tests.

The order of intercepts is important, but I may have my example backwards, not sure. The point is some have to be defined inside then blocks to get access to a fixture.

Here's a simple example:

// imagine fixtures have a nested array
beforeEach(() => {
  // The order of intercept is important
  cy.fixture(`my-${parameterized}-filename.json`)
    .as("fixtureAlias")
    .then(fixtureAlias => { cy.intercept("**/some/path?q1=foo", fixtureAlias) })
  cy.fixture(`my-${parameterized2}-filename.json`)
    .as("fixtureAlias2")
    .then(fixtureAlias2 => { cy.intercept("**/some/path?q1=foo&q2=bar", fixtureAlias2) })
  cy.intercept("**/some/path?q1=foo&q2=bar&q3=baz", { fixture: "my-simple-filename.json" } )
});

it("is a test", function() {
  cy.get("thing").should("have.length", this.fixtureAlias.nestedArray.length);
  cy.get("thing2").should("have.length", this.fixtureAlias2.nestedArray.length);
});

This is failing somewhere for me, whereas this works:

// imagine fixtures have a nested array
beforeEach(() => {
  cy.fixture(`my-${parameterized}-filename.json`).as("fixtureAlias");
  cy.fixture(`my-${parameterized2}-filename.json`).as("fixtureAlias2");
  // The order of intercept is important
  cy.intercept("**/some/path?q1=foo", `my-${parameterized}-filename.json`);
  cy.intercept("**/some/path?q1=foo&q2=bar", `my-${parameterized2}-filename.json`);
  cy.intercept("**/some/path?q1=foo&q2=bar&q3=baz", { fixture: "my-simple-filename.json" } )
});

it("is a test", function() {
  cy.get("thing").should("have.length", this.fixtureAlias.nestedArray.length);
  cy.get("thing2").should("have.length", this.fixtureAlias2.nestedArray.length);
});

I don't know if there's really much or any overhead defining each fixture twice, but is there any way to get something like the first pattern to work? Thanks

I just realized there's a way around this aliasing the intercepts and using cy.wait:

beforeEach(() => {
  // The order of intercept is important
  cy.intercept("**/some/path?q1=foo", { fixture: `my-${parameterized}-filename.json` }).as("interceptAlias1");
  cy.intercept("**/some/path?q1=foo&q2=bar", { fixture: `my-${parameterized2}-filename.json` }).as("interceptAlias2");
  cy.intercept("**/some/path?q1=foo&q2=bar&q3=baz", { fixture: "my-simple-filename.json" } )
});

it("is a test", function() {
  cy.wait("@interceptAlias1").then(interception => {
    cy.get("thing").should("have.length", interception.response.body.nestedArray.length);
  });
  cy.wait("@interceptAlias2").then(interception => {
    cy.get("thing2").should("have.length", interception.response.body.nestedArray.length);
  });
});
