示例1: TestStartStop

// TestStartStop is similar to Tests.TestStartStop except
// that it does not assume a pristine environment.
func (t *LiveTests) TestStartStop(c *gc.C) {
	t.PrepareOnce(c)
	t.UploadFakeTools(c, t.Env.Storage())

	inst, _ := testing.AssertStartInstance(c, t.Env, "0")
	c.Assert(inst, gc.NotNil)
	id0 := inst.Id()

	insts, err := t.Env.Instances([]instance.Id{id0, id0})
	c.Assert(err, gc.IsNil)
	c.Assert(insts, gc.HasLen, 2)
	c.Assert(insts[0].Id(), gc.Equals, id0)
	c.Assert(insts[1].Id(), gc.Equals, id0)

	// Asserting on the return of AllInstances makes the test fragile,
	// as even comparing the before and after start values can be thrown
	// off if other instances have been created or destroyed in the same
	// time frame. Instead, just check the instance we created exists.
	insts, err = t.Env.AllInstances()
	c.Assert(err, gc.IsNil)
	found := false
	for _, inst := range insts {
		if inst.Id() == id0 {
			c.Assert(found, gc.Equals, false, gc.Commentf("%v", insts))
			found = true
		}
	}
	c.Assert(found, gc.Equals, true, gc.Commentf("expected %v in %v", inst, insts))

	addresses, err := jujutesting.WaitInstanceAddresses(t.Env, inst.Id())
	c.Assert(err, gc.IsNil)
	c.Assert(addresses, gc.Not(gc.HasLen), 0)

	insts, err = t.Env.Instances([]instance.Id{id0, ""})
	c.Assert(err, gc.Equals, environs.ErrPartialInstances)
	c.Assert(insts, gc.HasLen, 2)
	c.Check(insts[0].Id(), gc.Equals, id0)
	c.Check(insts[1], gc.IsNil)

	err = t.Env.StopInstances(inst.Id())
	c.Assert(err, gc.IsNil)

	// The machine may not be marked as shutting down
	// immediately. Repeat a few times to ensure we get the error.
	for a := t.Attempt.Start(); a.Next(); {
		insts, err = t.Env.Instances([]instance.Id{id0})
		if err != nil {
			break
		}
	}
	c.Assert(err, gc.Equals, environs.ErrNoInstances)
	c.Assert(insts, gc.HasLen, 0)
}

示例2: TestInstanceAttributes

func (t *LiveTests) TestInstanceAttributes(c *gc.C) {
	inst, hc := testing.AssertStartInstance(c, t.Env, "30")
	defer t.Env.StopInstances(inst.Id())
	// Sanity check for hardware characteristics.
	c.Assert(hc.Arch, gc.NotNil)
	c.Assert(hc.Mem, gc.NotNil)
	c.Assert(hc.RootDisk, gc.NotNil)
	c.Assert(hc.CpuCores, gc.NotNil)
	c.Assert(hc.CpuPower, gc.NotNil)
	addresses, err := jujutesting.WaitInstanceAddresses(t.Env, inst.Id())
	// TODO(niemeyer): This assert sometimes fails with "no instances found"
	c.Assert(err, gc.IsNil)
	c.Assert(addresses, gc.Not(gc.HasLen), 0)

	insts, err := t.Env.Instances([]instance.Id{inst.Id()})
	c.Assert(err, gc.IsNil)
	c.Assert(len(insts), gc.Equals, 1)

	ec2inst := ec2.InstanceEC2(insts[0])
	c.Assert(ec2inst.DNSName, gc.Equals, addresses[0].Value)
	c.Assert(ec2inst.InstanceType, gc.Equals, "m1.small")
}
