func (*MockBinpackingLimiter) StopBinpacking 

func (p *MockBinpackingLimiter) StopBinpacking(context *context.AutoscalingContext, evaluatedOptions []expander.Option) bool

StopBinpacking stops the binpacking early, if we already have requiredExpansionOptions i.e. 1.

type MockReportingStrategy 

type MockReportingStrategy struct {
	// contains filtered or unexported fields
}

MockReportingStrategy implements expander.Strategy

func NewMockRepotingStrategy 

func NewMockRepotingStrategy(t *testing.T, optionToChoose *GroupSizeChange) *MockReportingStrategy

NewMockRepotingStrategy creates an expander strategy with reporting and mocking capabilities.

func (*MockReportingStrategy) BestOption 

func (r *MockReportingStrategy) BestOption(options []expander.Option, nodeInfo map[string]*schedulerframework.NodeInfo) *expander.Option

BestOption satisfies the Strategy interface. Picks the best option from those passed as an argument. When parameter optionToChoose is defined, it's picked as the best one. Otherwise, random option is used.

func (*MockReportingStrategy) LastInputOptions 

func (r *MockReportingStrategy) LastInputOptions() []GroupSizeChange

LastInputOptions provides access to expansion options passed as an input in recent strategy execution
