HaveField buffers stale fields #787
Description
I am using the following code to ensure that list.Items[] has exactly one element and that element has an empty Spec.Devices:
emptySlice := gomega.HaveField("Spec.Devices", gomega.BeEmpty())
gomega.Eventually(ctx, listSlices).WithTimeout(time.Minute).Should(gomega.HaveField("Items", gomega.ContainElements(emptySlice)))
My code under test incorrectly deleted all items (= list.Items[] empty). But the failure message then contained information about some previous item:
[FAILED] Timed out after 60.000s.
Value for field 'Items' failed to satisfy matcher.
Expected
<[]v1alpha3.ResourceSlice | len:0, cap:0>: nil
to contain elements
<[]*matchers.HaveFieldMatcher | len:1, cap:1>: [
{
Field: "Spec.Devices",
Expected:
{},
extractedField: <[]v1alpha3.Device | len:128, cap:170>[
{

Basic: {
Attributes: {

BoolValue: nil,

Gomega truncated this representation as it exceeds 'format.MaxLength'.
Consider having the object provide a custom 'GomegaStringer' representation
or adjust the parameters in Gomega's 'format' package.
