Introduction

In software development, functions are the building blocks of a program. They are reusable blocks of code that perform a specific task. However, when functions are called incorrectly, it can lead to errors and bugs in the program. In this article, we will discuss the concept of wrong called at functions and provide a comprehensive guide on how to avoid them.

What are Wrong Called at Functions?

Wrong called at functions refer to the incorrect way of calling a function in a program. This can occur when a function is called with the wrong arguments, or when the function is called in a way that is not intended by the programmer. Wrong called at functions can lead to errors, bugs, and even crashes in the program.

Example of Wrong Called at Functions

Let's take a look at an example of wrong called at functions in Python:

import unittest

import sys 
sys.path.append("src")

from model.app import *

class Programmed_savings_test(unittest.TestCase):

    def test_normal_1(self):
        amount = 300000
        interest = 0.035
        period = 24

        result = Calculate_programmed_savings(amount, interest, period)
        expected = 7451971.429
        self.assertAlmostEqual(expected, result, 2)

    def test_normal_2(self):
        amount = 500000
        interest = 0.06
        period = 36

        result = Calculate_programmed_savings(amount, interest, period)
        expected = 19079983.33
        self.assertAlmostEqual(expected, result, 2)

    def test_normal_3(self):
        amount = 1000000
        interest = 0.1
        period = 60

        result = Calculate_programmed_savings(amount, interest, period)
        expected = 65999990
        self.assertAlmostEqual(expected, result, 2)

    def test_normal_4(self):
        amount = 250000
        interest = 0.05
        period = 1

        result = Calculate_programmed_savings(amount, interest, period)
        expected = 262480
        self.assertAlmostEqual(expected, result, 2)

    def test_normal_5(self):
        amount = 200000
        interest = 0.045
        period = 12

        result = Calculate_programmed_savings(amount, interest, period)
        expected = 2507977.778
        self.assertAlmostEqual(expected, result, 2)

    def test_extraordinary_1(self):
        amount = 1000000
        interest = 0.02
        period = 1

        result = Calculate_programmed_savings(amount, interest, period)
        expected = 1019950
        self.assertAlmostEqual(expected, result, 2)

    def test_extraordinary_2(self):
        amount = 200000
        interest = 0.05
        period = 600

        result = Calculate_programmed_savings(amount, interest, period)
        expected = 125999980
        self.assertAlmostEqual(expected, result, 2)

    def test_extraordinary_3(self):
        amount = 500000
        interest = 1
        period = 12

        result = Calculate_programmed_savings(amount, interest, period)
        expected = 11999999
        self.assertAlmostEqual(expected, result, 2)

    def test_error_1(self):
        amount = 300000
        interest = -0.05
        period = 12

        with self.assertRaises(Invalidinterest):
            Calculate_programmed_savings(amount, interest, period)

    def test_error_2(self):
        amount = 500000
        interest = 0.06
        period = -12

        with self.assertRaises(Invalidmonths):
            Calculate_programmed_savings(amount, interest, period)

    def test_error_3(self):
        amount = 600000
        interest = 0
        period = 24

        with self.assertRaises(Invalidinterest):
            Calculate_programmed_savings(amount, interest, period)

    def test_error_4(self):
        amount = 400000
        interest = 1.5
        period = 12

        with self.assertRaises(Invalidinterest):
            Calculate_programmed_savings(amount, interest, period)

if __name__ == '__main__':
    unittest.main()

In this example, the Calculate_programmed_savings function is called with the wrong arguments in the test_error_1, test_error_2, test_error_3, and test_error_4 methods. This can lead to errors and bugs in the program.

Causes of Wrong Called at Functions

There are several causes of wrong called at functions, including:

Incorrect function signature: When a function is called with the wrong arguments, it can lead to errors and bugs in the program.
