fs := fakes.NewFakeFileSystem() content := "Hello, World!" fs.WriteFileString("/test/file.txt", content) str, err := fs.ReadFileString("/test/file.txt") if err != nil { log.Fatalf("Error reading file: %s", err) } fmt.Println(str) // Output: "Hello, World!"
fs := fakes.NewFakeFileSystem() _, err := fs.ReadFileString("/non/existant/file.txt") if err != nil { fmt.Println("File not found") }In this example, FakeFileSystem is used to simulate a read operation on a non-existent file. The function returns an error, and the code prints "File not found" to the console. Overall, the Go package library go github.com.cloudfoundry.bosh-utils.system.fakes is used for creating fake file systems for testing purposes. The ReadFileString method is used to read the contents of a file into a string variable.
