selective_assertions

selective_assertions 是一个 Rust 包，提供了测试中的灵活断言宏。它包括 assert_eq_excluding 和 assert_eq_selected，允许你在忽略指定字段或仅比较指定字段的情况下比较复杂结构。

特性

• assert_eq_excluding: 断言两个值相等，同时忽略指定字段。
• assert_eq_selected: 断言两个值的特定字段相等。

入门指南

安装

将 selective_assertions 添加到你的 Cargo.toml

[dependencies]
selective_assertions = "0.3.0"

用法

assert_eq_excluding

assert_eq_excluding 宏允许你在忽略指定字段的情况下断言两个值相等。这在比较复杂结构时很有用，其中某些字段可能不同，但与相等性检查无关。

use derive_getters::Getters;
use getset::Setters;
use selective_assertions::*;

// Debug and PartialEq are required for assert_eq!
// Clone, Getters, and Setters are required for assert_eq_excluding!
#[derive(Debug, PartialEq, Clone, Getters, Setters)]
#[set = "pub"]
struct User {
    id: u32,
    name: String,
    age: u32,
}

impl User {
    fn new(id: u32, name: &str, age: u32) -> Self {
        User { id, name: name.to_string(), age }
    }
}

fn main() {
    let user1 = User { id: 1, name: "Alice".to_string(), age: 10 };
    let user2 = User { id: 1, name: "Alice".to_string(), age: 20 };

    // This assertion will pass because the `age` field is excluded in the comparison.
    assert_eq_excluding!(user1, user2, age);
}

assert_eq_selected

assert_eq_selected 宏允许你断言两个值的特定字段相等。这在只需要比较指定字段，而不需要比较整个结构体或对象时很有用。

use derive_getters::Getters;
use selective_assertions::*;

// Debug and PartialEq are required for assert_eq!
// Getters is required for assert_eq_excluding!
#[derive(Debug, PartialEq, Getters)]
struct User {
    id: u32,
    name: String,
    age: u8,
}

fn main() {
    let user1 = User { id: 1, name: String::from("Alice"), age: 7 };
    let user2 = User { id: 1, name: String::from("Alice"), age: 8 };

    // Compare user1 and user2, focusing only on the `id` and `name` fields
    assert_eq_selected!(user1, user2, id, name);
}
