Consolidate Jest arrayContaining assertions

expect.arrayContaining can be used to validate an array containing multiple different elements, so multiple statements are not required.

Apply with the Grit CLI

grit apply jest_array_containing

Basic example

BEFORE

describe('test', () => {
  it('consolidates', async () => {
    const values = ['console.log($9o)', 'console.log($x)', 'PatternWithArgs($arg)'];
    const anotherValues = ['nine'];
    expect(values).toEqual(expect.arrayContaining([expect.stringContaining('console.log($9o)')]));
    expect(anotherValues).toEqual(expect.arrayContaining([expect.stringContaining('nine')]));
    expect(values).toEqual(expect.arrayContaining([expect.stringContaining('console.log($x)')]));
    expect(values).toEqual(
      expect.arrayContaining([expect.stringContaining('PatternWithArgs($arg)')]),
    );
  });
});

AFTER

describe('test', () => {
  it('consolidates', async () => {
    const values = ['console.log($9o)', 'console.log($x)', 'PatternWithArgs($arg)'];
    const anotherValues = ['nine'];
    expect(anotherValues).toEqual(expect.arrayContaining([expect.stringContaining('nine')]));
    expect(values).toEqual(
      expect.arrayContaining([
        expect.stringContaining('console.log($9o)'),
        expect.stringContaining('console.log($x)'),
        expect.stringContaining('PatternWithArgs($arg)'),
      ]),
