Rstest has been inspired by several outstanding projects in the community. We would like to acknowledge and express our sincere gratitude to the following projects:

• Several API design patterns have been influenced by Jest and Vitest.
• Some functions in Rstest are referenced from Vitest, such as the expect, expect.poll and snapshot API, etc.
