这是问题 write rust language unit test pub fn calculation_ema(array: &Vec<f64>, average: usize) -> Vec<f64> { let multiplier = 2.0 / (average as f64 + 1.0); let mut exponential_moving_average = array[0]; let mut result = vec![]; result.push(exponential_moving_average); for i in 1..array.len() { exponential_moving_average = array * multiplier + exponential_moving_average * (1.0 - multiplier); result.push(exponential_moving_average); } result } ++++++++++++++++++++++++++++++ 这是回答 Sure! Here's a unit test for the calculation_ema function in Rust: rust Copy code #[test] fn test_calculation_ema() { let array = vec![10.0, 12.0, 15.0, 20.0, 18.0]; let average = 3; let expected_result = vec![10.0, 11.0, 12.333333333333334, 15.11111111111111, 16.74074074074074]; let result = calculation_ema(&array, average); assert_eq!(result, expected_result); } This test creates an input array [10.0, 12.0, 15.0, 20.0, 18.0] and an average of 3, and expects the output of the calculation_ema function to be [10.0, 11.0, 12.333333333333334, 15.11111111111111, 16.74074074074074]. The test checks that the actual output matches the expected output using the assert_eq macro. |
