Selenium Webdriver (Part 3) - Dropdown

 static dropdown

- works only for dropdowns having web element with select as tagName.

WebElement staticdropdown = driver.findElement(By.id("")); 
Select dropdown = new Select(staticdropdown);

dropdown.selectByIndex(3);

dropdown.selectByValue("XYZ");

dropdown.selectByVisibleText("XYZ");

dropdown.getFirstSelectedOption().getText()

 dynamic dropdown

// parent - child relationship xpath; comment one of the two

Here one location can be in both From and TO dropdowns so we need to consider the From and TO Weblocators as parents and then
add the location as child.
Example below:

driver.findElement(By.xpath("//div[@id='ctl00_mainContent_ddl_originStation1_CTNR'] //a[@value='BLR']")).click();
Thread.sleep(2000);
driver.findElement(By.xpath("//div[@id='ctl00_mainContent_ddl_destinationStation1_CTNR'] //a[@value='MAA']")).click();

ctl00_mainContent_ddl_originStation1_CTNR - From locaton dropdown

ctl00_mainContent_ddl_destinationStation1_CTNR - To location dropdown

Selenium Webdriver (Part 2) - Waits

 Types of Waits:

1. Implicit Wait

2. Explicit Wait

1. Webdriver Wait
2. Fluent Wait

Implicit Wait-

Pros-

1. Declared globally. Wait for a max of n number of seconds before you throw error.

2. Readable code.

Cons-

1. Performance cause issues

2. if implicit wait is set to 20 s say, then we cannot find which components are slowly loading.

Explicit Wait-

Pros-

1. Specific to that locator only.

2. Wait is applied at only targeted elements. So no performance issues.

Cons-

1. More written code and disturbs readability.

_____________________________________________________________________________

Explicit Waits are of two types:

   1. Webdriver Wait

   2. Fluent Wait

Both implement the Wait interface.

FluentWait doesn't have methods to use, so we need to create custom methods for it to use it.

________________________________________________________________________________

Syntax/examples:

1. Fluent Wait

Wait<Webdriver> wait = new FluentWait<Webdriver>();

.withTimeout(10,SECONDS)

.pollingEvery(2,SECONDS)

.ignoring(NoSuchElementException.class)

2. Implicit Wait

driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS); // Duration.of(5) not working

3. Explicit Wait 

WebDriverWait wait = new WebDriverWait(driver, 10);

WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("element_id")));

wait.until(ExpectedConditions.textToBePresentInElementLocated(By.className("message"), "Success"));

wait.until(ExpectedConditions.alertIsPresent());

4. Thread.sleep

Halts the code for n seconds.

          

Selenium Webdriver (Part 1) - Locators

Locators

1. CSS Selectors
1. attribute      -- tagName[attribute='value']
2. className  -- tagName.className
3. Id                -- tagName#Id
4. parent to child traverse -- parentTagName childTagName
5. nth child     -- tagName[attribute='value']:nth-child(index) 
6. Regex Eg    -- "input[type*='pass']"
7. Notes -
1. child to parent traverse is not possible in CSS
2. tagName.className --> here tagName is optional, we can write .className also but the className should be unique.
3. class="submit signInBtn" --> here are 2 identifiers, we can choose any one of them.
2. XPath
1. attribute      -- //tagName[@attribute='value']
2. parent to child traverse -- //parentTagName/childTagName
3. index           -- //tagName[@attribute='value'][index]
4. Regex Eg    -- //button[contains(@class,'submit')]
5. parent to child to child traverse Eg -- //header/div/button[1]/following-sibling::button[1]
6. parent to child to parent to grandParent to child traverse Eg -- //header/div/button[1]/parent::div/parent::header/a
7. Notes - 
1. customized Xpath - both the words in the class name must be used. Eg: //button[@class='submit signInBtn']
3. ID, name, className 
1. just the ID/name/className respectively.
4. With text
1. linktext
2. normalized-space()='xyz'
3. xpath Eg- //button[text()='Log Out']

Reselling Arijit Singh Concert Tickets turned out to be a NightMare

 

I canceled my plan to attend Arijit Singh's Concert in GIFT City, Gujarat. 

I found Viagogo on the internet where you could resell your tickets. 

Tbh setting the selling price is a daunting task and finally, I deactivated my ticket listing there.

In this blog, you will learn from my experience why the resold tickets are so expensive and why people are selling at such high prices.

Viagogo adds handling charges , tax applied per ticket,

On sale, the seller receives the amount

via PayPal which charges

4.4% transaction fee

+ 0.30 fixed fee

+ 4% conversion fee

Upon this amount, Indian bank charges

25 dollars fixed transaction fee (if not a business)

+ 3% conversion fee.

After all this, you get money in the bank which is taxed 20-30% as income tax.

So, I bought tickets at 3177 Rs (including GST), but I have to sell them at 14000 Rs 

to make a profit of 147 Rs.

I am willing to sell for the same price of 3177 Rs, but I have not found a buyer in my circle yet.

Also, I wrote a java code just in case someone is looking to estimate the listing price on Viagogo.

public class Viagogo {


    public static void main(String[] args) {

        boolean paypalBusinessAccount = false;
        double ticketPriceActual = 1588.50; // including GST
        double numberOfTickets = 2;
        double ticketPriceListedonViagogo = 7000.00; // per ticket


        double viagogoHandlingFee = 854.00; // viagogo handling fee
        double viagogoTax = 154.00; // viagogo tax
        double paypalTransactionFeeDeducted = 0.956; // 4.4% transaction fee by Paypal
        double paypalFixedFee = 0.30; // fixed for USD
        double paypalCurrencyConversionDeducted = 0.96; // 4% conversion fee by Indian Bank
        double indianBankRemittanceFee = 2140.00; // 25$ transaction fee
        double indianBankRemittanceConversionDeducted = 0.97; // 3% conversion fee by Indian Bank
        double indianIncomeTaxDeducted = 0.80;
        double amountReceivedInBank;

        double finalResoldTicketPrice = ticketPriceListedonViagogo + viagogoHandlingFee + viagogoTax;

        double amountReceivedAndDetectedByIndianBank = (ticketPriceListedonViagogo*paypalTransactionFeeDeducted-paypalFixedFee)*paypalCurrencyConversionDeducted;


        if(paypalBusinessAccount==false)
        {
            amountReceivedInBank = (amountReceivedAndDetectedByIndianBank-indianBankRemittanceFee)*indianBankRemittanceConversionDeducted;
        }else
        {
            amountReceivedInBank = amountReceivedAndDetectedByIndianBank;
        }

        double profitFromResale = amountReceivedInBank*indianIncomeTaxDeducted-ticketPriceActual*numberOfTickets;

        System.out.println("Profit: "+ Math.round(profitFromResale));
        System.out.println("Expected to be Credited in Bank Account: "+ Math.round(amountReceivedAndDetectedByIndianBank));
        System.out.println("Final Ticket Price to the Buyer: "+ Math.round(finalResoldTicketPrice));



    }

Here's a detailed guide on the health benefits and best practices when drinking water:

1. Health Benefits of Drinking Water:

1. Hydration: Water is essential for maintaining the body's fluid balance, which is vital for regulating temperature, removing waste, and supporting bodily functions.
2. Improved Digestion: Water helps break down food and absorb nutrients. It also prevents constipation by keeping the digestive tract hydrated.
3. Skin Health: Drinking enough water keeps the skin hydrated and can help reduce the appearance of wrinkles, dryness, and acne.
4. Boosts Energy: Dehydration can lead to fatigue, but drinking water helps maintain energy levels and supports mental clarity.
5. Detoxification: Water flushes out toxins through urine and sweat, helping the kidneys function efficiently.
6. Weight Management: Drinking water can help curb appetite and reduce calorie intake, which may aid in weight loss.
7. Joint Lubrication: Water helps maintain proper lubrication of joints, preventing conditions like arthritis.
8. Regulates Body Temperature: Staying hydrated helps maintain body temperature, especially during exercise or hot weather.
9. Improves Kidney Function: Proper hydration helps the kidneys filter waste and prevent kidney stones.

2. Dos and Don’ts of Drinking Water:

• Dos:
  • Drink water throughout the day, not just when thirsty.
  • Carry a water bottle with you to stay hydrated at all times.
  • Start your day with a glass of water to rehydrate after a night of sleep.
  • Drink water before, during, and after exercise to replenish lost fluids.
  • Drink water when you feel hungry, as thirst can sometimes be mistaken for hunger.
• Don’ts:
  • Don’t drink excessive amounts of water in one sitting, as it can lead to water intoxication.
  • Don’t rely solely on sugary drinks or caffeine to hydrate.
  • Avoid drinking large amounts of water right before bedtime to prevent disruptions in sleep from frequent trips to the bathroom.
  • Don’t drink water that is contaminated or not filtered, as it can cause health problems.
  • Don’t wait until you feel thirsty to drink water, as this can be a sign of early dehydration.

3. How Much Water Should You Drink Every Day?

• A common recommendation is to drink 2-3 liters of water per day, but this can vary based on individual needs. Factors such as age, sex, activity level, climate, and overall health play a role in determining how much water you need.
• General Guidelines:
  • Men: About 3.7 liters daily, including all fluids.
  • Women: About 2.7 liters daily, including all fluids.
• Listen to Your Body: Thirst is a good indicator, but ensure you’re drinking enough throughout the day to maintain hydration.

4. When NOT to Drink Water:

• Right After Meals: Avoid drinking large amounts of water immediately after meals, as it can dilute stomach acid and hinder digestion.
• During Intense Exercise: While hydration is crucial during exercise, drinking excessive amounts of water in a short period during intense activity can cause water intoxication or hyponatremia (low sodium levels in the blood).
• If You Have Certain Medical Conditions: If you have kidney disease, heart conditions, or are on a restricted fluid intake, consult a doctor before consuming large amounts of water.
• When You’re Already Hydrated: If you’ve already consumed enough water throughout the day, avoid forcing more water into your system to prevent overhydration.

5. Which is More Beneficial: Tap Water, Mineral Water, or Sparkling Water?

• Tap Water:
  • Pros: Convenient, affordable, and often contains essential minerals like calcium and magnesium, depending on the source.
  • Cons: In some areas, tap water can contain contaminants like chlorine, lead, or pesticides. It’s important to check your local water quality.
• Mineral Water:
  • Pros: Rich in minerals like calcium, magnesium, and sodium, which can support hydration and provide nutritional benefits.
  • Cons: Can be more expensive and may have a higher sodium content depending on the brand.
• Sparkling Water:
  • Pros: Often enjoyable as a refreshing, fizzy alternative to still water and may help with digestion.
  • Cons: Some brands contain added sugars or artificial sweeteners. Overconsumption may also contribute to bloating and gas due to carbonation.

Verdict: All types of water are beneficial, but mineral water may offer extra benefits due to its higher mineral content. Tap water is the most economical and often just as good if filtered properly. Sparkling water is a healthy, enjoyable option but should be consumed in moderation.

6. Cold vs Hot Drinking Water Benefits:

• Cold Water:
  • Pros: Cold water can help cool down the body, especially after physical activity or in hot weather.
  • Cons: Drinking ice-cold water may sometimes cause discomfort, such as throat irritation or triggering headaches in sensitive individuals.
• Hot Water:
  • Pros: Hot water is great for digestion, as it helps relax the digestive tract. It can also be soothing for sore throats and reduce congestion.
  • Cons: Too hot water can burn the mouth or throat. It’s best to drink it at a moderate temperature.

Verdict: Both have benefits depending on your needs. Cold water is ideal for cooling down, while hot water can support digestion and provide comfort.

7. How Much Water Should You Drink at a Time?

• The body can absorb water more efficiently when consumed in smaller amounts throughout the day.
• Ideal Intake per Sitting: Around 250-300 milliliters (about one cup) is recommended. Drinking too much at once can overwhelm the kidneys and lead to water retention.
• Best Practice: Drink water regularly throughout the day rather than in large quantities at once. This helps maintain hydration without overwhelming your system.
