Description

refactor-jasmine-vitest skips createSpyObjs if they are only providing one argument. The test are hinting that a call like jasmine.createSpyObj('MyService') is not handlable.

But the first argument doesn't have to be a base name. In fact it is optional

createSpyObj(baseName (opt), methodNames, propertyNames (opt)), see https://jasmine.github.io/api/5.12/jasmine.html

Currently something like

const loggerSpy = jasmine.createSpyObj<LoggingService>(['error']);

is transformed to

// TODO: vitest-migration: jasmine.createSpyObj called with a single argument is not supported for transformation. See: https://vitest.dev/api/vi.html#vi-fn
const loggerSpy = jasmine.createSpyObj<LoggingService>(['error']);

expected output:

const loggerSpy = { error: vi.fn() };

Minimal Reproduction

• follow steps on https://angular.dev/guide/testing/migrating-to-vitest
• call ng g @schematics/angular:refactor-jasmine-vitest

example spec file:

describe('Foo', () => {
 let loggerSpy: jasmine.SpyObj<LoggingService>;

  beforeEach(() => {
    loggerSpy = jasmine.createSpyObj<LoggingService>(['error']);
  });

  it('should be fine', () => {
    expect(loggerSpy).toBeTruthy();
  });
});
