1.断言用assert,可以进行==,!=,+,-,*,/,<=,>=,is True.False,is not True.False ,in ,not in 等判断. import pytestdef add(a,b): return a + b def is_prime(n): if n <= 1: return False for i in range(2,n): if n % i == 0: return False return True def test_add_1(): '
#pytest 的基本用法# 安装: pip install pytest#在当前目录下运行 : 输入 pytest# 1.断言#功能:用于计算a与b相加的和def add(a,b): return a + b#功能:用于判断素数def is_prime(n): if n < 1: return False for i in range(2,n): if n % i == 0: return False return True#测试相等def test_add_1(): assert add(3
