Ethereum: Can you use a Fuzz test with random parameters in setup () Fourge?

Fuzz testing is an essential aspect that ensures the reliability and security of Ethereum Smart contracts. This includes random or unexpected input input in order to check the behavior of the contract under a variety of conditions. In this article, we will investigate how the Fuzz test using random parameters in the SETUP () function on the Forge system.

Problem:

When creating a new contract or module, you must define the Setup () function before performing the tests to perform all the necessary setup tasks. However, the Setup () feature is not intended to directly handle random entrances. Instead of being able to initiate variables pre -defined values ​​or constant.

Solution:

To get a Fuzz test with the random parameters for Forge, you can create a custom SETUP () feature that creates random values ​​of your contract parameters using libraries such as “accidental”. Here’s an example of how you can modify the Setup () feature to achieve this:

`Python

Imported by accident

Class FuzzedethereumContract:

Def Setup (I):

Generate 10 random integers from 0 to 100

self.x = [random.randint (0, 100) _ range (10)]]]]

Generate a random float value from 1.0 to 2.0

self.y = round (random.Uniform (1.0, 2.0), 4)

`

In this example, we create two sets of random integers (x" and "y") and one random float value using "random.Randint (), random.uliform () and round ()"

Run Fuzz tests:

You can use the Forge Testing Framework to perform your contract Fuzzi tests. Here's an example of how to create a Fuzz Test Kit:

Python

Import a seamless one

From Fuzz Import Fuzz

Class testfuzzedethereumcontract (Unittest.testcase):

Def Setup (I):

SELF.Contract = FuzzedethereumContract ()

Def Fuzztest (SELF, for days = None):

If no parameters are provided, create some random values

If the days are not available:

x = [random.randint (0, 100) _ range (10)]]]

y = round (random.UMForm (1.0, 2.0), 4)

Fuzz Try the Treatment Function of the Contract with Generalized Parameters

Fuzz.ruffle (x + y)

Return the truth

If __name__ == ‘__main__’:

Unittest.main ()

`

In this example, we create a Testfuzzedethereumcontract, which is inherited from Unitest.testcase. The Setup () method creates some random values ​​of contract parameters. Then we define the Fuzz test function (Fuzztest ()), which takes the optional parameter parameter (i.e. map list containing the input parameters of the contract). If you are not presented for the days, we create some random values ​​and take the Fuzz test.

Conclusion:

By modifying your Setup () feature to generate random value by using libraries such as Random, you can create optional Ethereum smart contract tests for Forge. This approach suggests that the behavior of your contract is strong from the unexpected input and helps determine possible security vulnerabilities.
