How to read a JSON file and validate the response against the schema.

Install the following requirements:

• pip install jsonschema

Use the below code to read a JSON:

def readJSONFile(fileName):

        data = open(fileName)

        jsonData = json.load(data)

        return jsonData

Use the below code to validate a JSON schema:

def validate_schema(json_data, json_schema):

        try:

            validate(instance=json_data, schema= json_schema)

        except jsonschema.exceptions.ValidationError as err:

            assert False, "JSON schema is not matching, Please check"

How to call C# code from Python -

Install - pip install clr

pip install --pre pythonnet

Please find the below example -

C# Code :

namespace PrintYourName

{

    [ComVisible(true)]

    public class Test

    {

        public int DoSum(int a, int b)

        {

            return a + b;

        }

        public int DoSub(int a, int b)

        {

            return a - b;

        }

        public int DoMul(int a, int b)

        {

            return a * b;

        }

        public string printName()

        {

            return "Balaji";

        }

        public static string GetZonedDateTime()

        {

            DateTime dateTime = DateTime.Now;

            string zonedDateTime = string.Format("{0:yyyy-MM-ddTHH:mm:ss.fffZ}", dateTime.ToLocalTime());

            return zonedDateTime;

        }

    }

}

Python Code:

import clr

import sys

print(sys.version)

lb = clr.AddReference(r"C:\Project\Automation\PrintYourName\obj\Debug\net6.0\PrintYourName.dll")

from C#NameSpace import ClassName

from PrintYourName import Test

# from System.IO import *

# from System.Convert import *

c= Test()

print("Addition Result is", c.DoSum(10,10))

print("Subtraction Result is", c.DoSub(12,10))

print("Multiply Result is", c.DoMul(20,10))

print("Name is ", c.printName())

How to pass parameters to the dotnet test command while using NUnit

If you want to avoid a runsettings file, you can use this workaround

Tests.cs

string browser = System.Environment.GetEnvironmentVariable("Browser") ?? "chrome";

Note: Selection of browser is through an environment variable. Defaults to Chrome if unprovided.

Tests.bat

set DIR=%~dp0

chdir /d %DIR% 

SETLOCAL

SET Browser=firefox

dotnet test project.dll --filter TestCategory="Sanity"

If you want to launch the test from an Azure DevOps (fka VSTS or TFS) pipeline, you can simply use the $(...) notation to inline variables

SET TestPassword=$(TestPassword)

dotnet test $(Build.SourcesDirectory)\MyCompany.MyProduct.UITests\MyTest.csproj --configuration $(BuildConfiguration) --collect "Code Coverage" --logger trx --results-directory $(Agent.TempDirectory)

Suppose you are given with a day name, and a number (int value), you need to write a code to determine the number of days after the given day is which day ?

Asked this question in one of the leading MNC.

// Eg.  

// Input: Day = Sunday  & number = 4

// Output: Wednesday

 // Eg.

// Input: Day = Thursday & number = 9

// Output: Friday

import java.util.*;

 class Solution

{   

    public String solution(String day, int number)

    {

        String days[]={"Sunday", "Monday", "Tuesday","Wednesday","Thursday","Friday","Saturday"};

        String output=null;

        for(int i=0;i<days.length;i++)

        {

            if(days[i]==day)

            {

                output = days[(i+number-1)%7];

                break;

            }

        }

         return output;

    }

}

class Main 

{

    public static void main(String[] args)

    { 

        String ans = new Solution().solution("Sunday",21);

        System.out.println(ans);

    }

}

Find occurrences of a character without using loops and conditions -

String str = "Balaji"; //Find how many times 'a' is repeating

System.out.println(str.split("a").length-1);

How to set the generated token as an Environment Variable in Postman Tool

Generated Token Response -

{

    "data": {

        "authToken": {

            "getToken": {

                "accessToken": "b1hXMCJ9.eyJhdWETQ1NTk2NSwiYWlvIjoiCJhcHBpZCI6IjQ1ZTMA"

            }

        }

    }

}

Use the below code snippet to set the generated token as an environment variable in Postman Tool

Paste the below code in the Test tab (Please modify the code according to your response).

Environment Variable: token (Use this variable across the API's)

Example: In headers - Authorization : {{token}}

var responseObject = JSON.parse(responseBody);

if (responseObject && responseObject.data && responseObject.data.authToken && 

responseObject.data.authToken.getToken  && responseObject.data.authToken.getToken.accessToken)

{

    postman.setEnvironmentVariable("token", `Bearer ${responseObject.data.authToken.getToken.

                                                            accessToken}`);

}
