Pytest -断言、跳过及运行

基本断言方法:

　　

Pytest框架assert断言使用

　　

• 断言:支持显示最常见的子表达式的值，包括调用，属性，比较以及二元和一元运算

符。
• 包含，相等，不等，大于 小于运算，assertnot 假

• assert “h” in “hello”(判断h在hello中)

• assert 3==4(判断3=4)

• assert 3!=4(判断3!=4)

• assert f() ==4 (判断f()方法返回值是否=4)

• assert 5>6 (判断5>6为真)

• assert not xx (判断xx不为真)

• assert {'0', '1', '3', '8'} == {'0', '3', '5', '8'}

• import pytest
  
  def test_one():
      assert 1 != 2

      assert {"name": "linda", "age": 19} == {"name": "linda", "age": 19}

      assert (1 < 2) == True
  
  def f():
      return 3
  
  def test_two():
      assert f() == 3
