generate test cases for the following rust code: fn calculate_weight_on_mars(weight: f32) -> f32 { (weight / 9.81) * 3.711 }
Sure, here are some test cases you can use to validate the calculate_weight_on_mars function:
- Case with positive weight
- Input:
calculate_weight_on_mars(70.0) - Expected output:
28.35434
- Case with zero weight
- Input:
calculate_weight_on_mars(0.0) - Expected output:
0.0
- Case with negative weight
- Input:
calculate_weight_on_mars(-50.0) - Expected output:
-20.26828
- Case with very small weight (near zero)
- Input:
calculate_weight_on_mars(0.01) - Expected output:
0.0038921586
- Case with very large weight (near the maximum for a 32-bit float)
- Input:
calculate_weight_on_mars(3.4028235E+38) - Expected output:
1.3057194E+38
Generate the code for the test cases
Certainly! Here's some Rust code that you can use to test the calculate_weight_on_mars function with the test cases I provided earlier:
rustCopy codefn main() {
// Test case 1
let mars_weight = calculate_weight_on_mars(70.0);
assert_eq!(mars_weight, 28.35434);
// Test case 2
let mars_weight = calculate_weight_on_mars(0.0);
assert_eq!(mars_weight, 0.0);
// Test case 3
let mars_weight = calculate_weight_on_mars(-50.0);
assert_eq!(mars_weight, -20.26828);
// Test case 4
let mars_weight = calculate_weight_on_mars(0.01);
assert_eq!(mars_weight, 0.0038921586);
// Test case 5
let mars_weight = calculate_weight_on_mars(3.4028235E+38);
assert_eq!(mars_weight, 1.3057194E+38);
}
fn calculate_weight_on_mars(weight: f32) -> f32 {
(weight / 9.81) * 3.711
}
You can run this code to test the calculate_weight_on_mars function using the test cases I provided. The assert_eq! macro will check that the actual output of the function matches the expected output for each test case, and will panic if there is a mismatch.
write test cases for the following rust code: fn main() { println!("Enter your weight (kg)"); let mut input = String::new(); io::stdin().read_line(&mut input).unwrap(); println!("INput: {}", input); //borrow_input(&input); //move_input(input); let in_weight: f32 = input.trim().parse().expect("Invalid input"); let mars_weight = calculate_weight_on_mars(in_weight); println!("Weight on mars:{} kg", mars_weight); }
The code you provided contains user input, which can be difficult to test automatically. However, we can still test the calculate_weight_on_mars function separately from the user input portion of the code. Here are some test cases you can use to validate the calculate_weight_on_mars function:
- Case with positive weight
- Input:
calculate_weight_on_mars(70.0) - Expected output:
28.35434
- Case with zero weight
- Input:
calculate_weight_on_mars(0.0) - Expected output:
0.0
- Case with negative weight
- Input:
calculate_weight_on_mars(-50.0) - Expected output:
-20.26828
- Case with very small weight (near zero)
- Input:
calculate_weight_on_mars(0.01) - Expected output:
0.0038921586
- Case with very large weight (near the maximum for a 32-bit float)
- Input:
calculate_weight_on_mars(3.4028235E+38) - Expected output:
1.3057194E+38
To test the user input portion of the code, you can use Rust's built-in std::io::Cursor type to simulate user input. Here's an example of how to test the user input portion of the code for the case where the user enters a valid weight:
rustCopy codeuse std::io::{self, Read};
use std::io::Cursor;
fn main() {
let mut input = Cursor::new("70.0\n"); // simulate user input
let mut buffer = String::new();
input.read_line(&mut buffer).unwrap();
let in_weight: f32 = buffer.trim().parse().expect("Invalid input");
let mars_weight = calculate_weight_on_mars(in_weight);
assert_eq!(mars_weight, 28.35434);
}
fn calculate_weight_on_mars(weight: f32) -> f32 {
(weight / 9.81) * 3.711
}
This code uses a Cursor to simulate the user typing "70.0" and pressing enter. The read_line method reads from the Cursor and puts the user input into a buffer, which is then parsed into a f32 using trim and parse. Finally, the calculate_weight_on_mars function is called with the user's weight as input, and the output is checked against the expected value using the assert_eq! macro. You can use a similar approach to test the user input portion of the code for the other test cases.
I'm sorry, I didn't receive a question. Is there anything else you'd like me to help you with?
