Question 1

How do I generate fake data for a Go struct with nested fields?

Accepted Answer

Use the Struct method by passing a pointer to your struct. For nested fields, like the Bar struct in the README, it automatically handles them without extra configuration. You can add tags for fine-grained control.

Question 2

Gofakeit vs Faker for Go: which is better?

Accepted Answer

Gofakeit has more functions (310+ vs Faker's ~100) and features like struct tags and custom functions. Choose Gofakeit for extensive built-in data and Go-specific integration; Faker might be simpler for basic needs.

Question 3

Can I create CSV files with random data using Gofakeit?

Accepted Answer

Yes, use the CSV function with CSVOptions. You can pass nil for auto-generation or customize columns. The output is byte data that can be written to a file, ideal for testing data pipelines.

Question 4

How to seed Gofakeit for reproducible tests?

Accepted Answer

Call gofakeit.Seed(number) with a specific seed. For example, Seed(8675309) ensures the same random data is generated each time, which is crucial for consistent unit testing outcomes.

Question 5

Does Gofakeit support generating data for custom types?

Accepted Answer

Yes, implement the Fakeable interface for custom types to control generation. The README shows examples with Friend string and Age time.Time, allowing tailored data without modifying structs.

Question 6

How to extend Gofakeit with my own data generators?

Accepted Answer

Use AddFuncLookup to define custom functions with Generate logic and parameters. This lets you use them in struct tags or other contexts, as demonstrated with 'jumbleword'.
