ginkgo-linter: wrong comparison assertion. Consider using `Expect(p1).To(BeIdenticalTo(p2))` instead

ginkgo-linter: comparing a pointer to a value will always fail. Consider using `Expect(p1).ToNot(HaveValue(Equal(6)))` instead

ginkgo-linter: comparing a pointer to a value will always fail. Consider using `Expect(p1).ToNot(HaveValue(Equal(6)))` instead

ginkgo-linter: multiple issues: timeout defined more than once; polling defined more than once

ginkgo-linter: multiple issues: only use time.Duration for timeout and polling in Eventually() or Consistently(); only use time.Duration for timeout and polling in Eventually() or Consistently(). Consider using `Consistently(func() bool { return true }, time.Second*10, time.Second).Should(BeTrue())` instead

ginkgo-linter: timeout must not be shorter than the polling interval

ginkgo-linter: Success matcher only support a single error value, or function with Gomega as its first parameter

ginkgo-linter: wrong error assertion. Consider using `Eventually(func() error { return err }).Should(Succeed())` instead
