From b540c6df253c1f528486bf4245da8eec66710684 Mon Sep 17 00:00:00 2001 From: Remo Senekowitsch Date: Sat, 14 Sep 2024 09:48:26 +0200 Subject: [PATCH] Make if2 less confusing Some people would get stuck on this exercise, trying to understand the meaning behind foo, fuzz, baz etc. Making the theme of the code make a little more sense to humans should hopefully prevent people from getting confused by abstract and non-sensical tests. --- exercises/03_if/if2.rs | 22 ++++++++++++---------- solutions/03_if/if2.rs | 26 ++++++++++++++------------ 2 files changed, 26 insertions(+), 22 deletions(-) diff --git a/exercises/03_if/if2.rs b/exercises/03_if/if2.rs index 593a77a7..10037f26 100644 --- a/exercises/03_if/if2.rs +++ b/exercises/03_if/if2.rs @@ -1,7 +1,7 @@ // TODO: Fix the compiler error on this function. -fn foo_if_fizz(fizzish: &str) -> &str { - if fizzish == "fizz" { - "foo" +fn picky_eater(food: &str) -> &str { + if food == "strawberry" { + "Yummy!" } else { 1 } @@ -18,18 +18,20 @@ mod tests { use super::*; #[test] - fn foo_for_fizz() { - // This means that calling `foo_if_fizz` with the argument "fizz" should return "foo". - assert_eq!(foo_if_fizz("fizz"), "foo"); + fn yummy_food() { + // This means that calling `picky_eater` with the argument "food" should return "Yummy!". + assert_eq!(picky_eater("strawberry"), "Yummy!"); } #[test] - fn bar_for_fuzz() { - assert_eq!(foo_if_fizz("fuzz"), "bar"); + fn neutral_food() { + assert_eq!(picky_eater("potato"), "I guess I can eat that."); } #[test] - fn default_to_baz() { - assert_eq!(foo_if_fizz("literally anything"), "baz"); + fn default_disliked_food() { + assert_eq!(picky_eater("broccoli"), "No thanks!"); + assert_eq!(picky_eater("gummy bears"), "No thanks!"); + assert_eq!(picky_eater("literally anything"), "No thanks!"); } } diff --git a/solutions/03_if/if2.rs b/solutions/03_if/if2.rs index 440bba05..21c0dcd3 100644 --- a/solutions/03_if/if2.rs +++ b/solutions/03_if/if2.rs @@ -1,10 +1,10 @@ -fn foo_if_fizz(fizzish: &str) -> &str { - if fizzish == "fizz" { - "foo" - } else if fizzish == "fuzz" { - "bar" +fn picky_eater(food: &str) -> &str { + if food == "strawberry" { + "Yummy!" + } else if food == "potato" { + "I guess I can eat that." } else { - "baz" + "No thanks!" } } @@ -17,17 +17,19 @@ mod tests { use super::*; #[test] - fn foo_for_fizz() { - assert_eq!(foo_if_fizz("fizz"), "foo"); + fn yummy_food() { + assert_eq!(picky_eater("strawberry"), "Yummy!"); } #[test] - fn bar_for_fuzz() { - assert_eq!(foo_if_fizz("fuzz"), "bar"); + fn neutral_food() { + assert_eq!(picky_eater("potato"), "I guess I can eat that."); } #[test] - fn default_to_baz() { - assert_eq!(foo_if_fizz("literally anything"), "baz"); + fn default_disliked_food() { + assert_eq!(picky_eater("broccoli"), "No thanks!"); + assert_eq!(picky_eater("gummy bears"), "No thanks!"); + assert_eq!(picky_eater("literally anything"), "No thanks!"); } }
