如何在python中测试类？

我使用spyder定义了这个类，为了测试这个类，我的老师会创建一个新的文件进行测试，他会检查每个方法是否返回了所需的结果，有人能告诉我怎么做吗

class Caminhos():
    
    def __init__(self,vi,vf):
        self._vi = vi
        self._vf = vf
        self._caminhoI = [vi, vf]
        
    def primeiroV(self):
        return self._caminhoI[0]
    
    def ultimoV(self):
        return self._caminhoI[-1]
    
    def comprimento(self):
        return len(self._caminhoI)

    def acrescentaV(self, v):
        self._caminhoI=self._caminhoI + [v]
    
    def pertenceQ(self, v):
        i = 0
        b = False
        while i < len(self._caminhoI) and not b:
            if self._caminhoI[i] == v:
                b = True
            i = i + 1
        return b
        
    def verticePos(self, v):
    #aqui preferia aplicar a pertenceQ ao V mas n sei bem a sintaxe
        i = 0              
        b = False
        while i < len(self._caminhoI) and not b:
            if self._caminhoI[i] == v:
                b = True
            i = i + 1
        if not b:
            print("Erro, o vertice nao pertence ao caminho")
        else:
            i = 0
            d = False
            while i < len(self._caminhoI) and not d:
                if self._caminhoI[i] == v:
                    d = True
                i = i + 1
            return i
        
    def mostra(self):
        return self._caminhoI

class Caminhos（）：
定义初始值（自、vi、vf）：
自我。_vi=vi
自。_vf=vf
赛尔夫·卡米尼奥=[vi，vf]
def primeiroV（自我）：
返回自我。\u caminhoI[0]
def ultimoV（自）：
返回自我。卡米尼奥[-1]
def压缩机（自身）：
回程透镜（自身）
def acrescentaV（自身，v）：
self.\u caminhi=self.\u caminhi+[v]
def pertenceQ（自我，v）：
i=0
b=错误
而我（自我）而不是b：
如果self._caminhoI[i]==v：
b=正确
i=i+1
返回b
def verticePos（自身，v）：
#我更喜欢一份工作，一份工作
i=0
b=错误
而我（自我）而不是b：
如果self._caminhoI[i]==v：
b=正确
i=i+1
如果不是b：
打印（“Erro，o vertice nao pertence ao caminho”）
其他：
i=0
d=假
当我

定义类后，可以使用Spyder创建一个新文件来测试每个方法。创建一个新的python文件（您可以称之为Testing.py），确保它与前面定义的类的文件位于同一文件夹中，并且您可以执行下一个代码来测试您的类：

# Assuming your file is called "Caminhos" and it is in the same folder as this python script
# Import every method of your class 
from Caminhos import *


# Instantiate class object using the built-in function __init__()
c1 = Caminhos(4,6)

# Use "." after the object to call each method

# See object using mostra() method
print(c1.mostra())

# Get first element using primeiroV() method
print("Primeiro elemento: {}".format(c1.primeiroV()))

# Get first element using ultimo() method
print("Ultimo elemento: {}".format(c1.ultimoV()))

# Get length using comprimento() method
print("Comprimento: {}".format(c1.comprimento()))

# Add element using comprimento() method
c1.acrescentaV(1)
print(c1.mostra())

# See if there is a number in object using pertenceQ() function
print(c1.pertenceQ(8))
print(c1.pertenceQ(4))

# See if there is a number in object using verticePos() function
print(c1.verticePos(4))
