Disallow the use of duplicate suite names (no-suite-dupes)

Jasmine uses describe to begin and name a test suite.

Multiple suites with the same name is confusing and is an indicator of a copy-paste error.

Rule details

This rule triggers a warning (is set to 1 by default) whenever it encounters duplicated suite names.

Block mode (default)

The following patterns are considered warnings:

describe("Same suite name", function() {});
describe("Same suite name", function() {});

describe("Unique parent", function(){
  describe("Same suite name", function() {});
});
describe("Different parent", function(){
  describe("Same suite name", function() {});
});

The following patterns are not warnings:

describe("The first suite name", function() {});
describe("The second suite name", function() {});

Branch mode

In this mode, describe can share the same description unless the branch they form has already be defined.

The following patterns are considered warnings:

describe("Parent context", function(){
  describe("Same branch", function(){
    // ...
  });
  describe("Same branch", function(){
    // ...
  });
});

The following patterns are not warnings:

describe("Some context", function(){
  describe("Same branch", function(){
    // ...
  });
});
describe("Another context", function(){
  describe("Same branch", function(){
    // ...
  });
});
