fix(router-view): register instance in init hook (fix #2561)

[zrh122]

close #2561

[posva]

Hey could you add a test for this?

An e2e test should do it

[zrh122]

Yes, i will.

[zrh122]

@posva , e2e test added.

[posva]

Thanks, I'm merging this locally after applying some modifications (splitting the e2e test to keep the navigation guard one in an existing e2e test and the keep alive in another

[posva]

Merged locally!

@posva the e2e test for #2561 may be not correct. I removed the code (register instance in init hook), and executed npm run test:e2e, all the test case was passed. It should not be passed as i expect.

mine:

// routes
[
  // foo1
  { path: '/foo1', component: Foo },

  // foo2, same component as foo1
  { path: '/foo2', component: Foo },

  // bar
  { path: '/bar', component: Bar }
]

click order: /foo1 -> /bar -> /foo2

yours:

// routes
[  
  {
    path: '/with-guard1',
    name: 'with-guard1',
    component: WithGuard
  },
  {
    path: '/with-guard2',
    name: 'with-guard2',
    component: WithGuard
  }
]

click order: /with-guard1 -> /with-guard2 -> /with-guard1

maybe you can add another route, and the click order can be:

/with-guard1 -> /another -> /with-guard2

[posva]

Right! Thanks for checking, I'm going to fix the test
