Why App store submission testing in Testing Fundamentals? - Purpose & Use Cases

The Big Idea

What if a simple test could save your app from rejection and unhappy users?

The Scenario

Imagine you finished building your mobile app and want to share it with the world through an app store. You try to upload it without checking if it meets all the store rules and works well on different devices.

The Problem

Without proper testing, your app might get rejected by the store, or worse, users might face crashes and bugs. Fixing these problems after submission wastes time and frustrates users.

The Solution

App store submission testing helps you catch issues early by simulating the store's checks and testing your app on various devices. This way, you fix problems before submitting, making approval smoother and users happier.

Before vs After

✗ Before

Upload app directly
Wait for rejection
Fix bugs
Repeat

✓ After

Run submission tests
Fix issues early
Submit with confidence

What It Enables

It enables smooth app approval and a better experience for users right from the start.

Real Life Example

A developer tested their app with submission tools and caught a missing privacy policy link before submitting. The app was approved quickly, avoiding delays and bad reviews.

Key Takeaways

Manual submission without testing leads to delays and frustration.

Submission testing finds problems early to save time.

It helps your app get approved faster and work better for users.

Practice

1. What is the main purpose of app store submission testing?

easy

A. To ensure the app works correctly and meets store rules

B. To write the app's source code

C. To design the app's user interface

D. To create marketing materials for the app

Solution

1. Step 1: Understand app store submission testing

   This testing checks if the app functions well and follows the app store's guidelines.

2. Step 2: Differentiate from other app tasks

   Writing code, designing UI, and marketing are separate tasks not related to submission testing.

3. Final Answer:

   To ensure the app works correctly and meets store rules -> Option A

4. Quick Check:

   Submission testing = check app works and follows rules [OK]

Hint: Submission testing checks app function and rules compliance [OK]

Common Mistakes:

• Confusing testing with coding or design
• Thinking marketing is part of submission testing
• Ignoring app store rules during testing

2. Which of the following is the correct way to test an iOS app before submission?

easy

A. Use TestFlight to distribute the app to testers

B. Upload the app directly to the App Store without testing

C. Test only on the iOS Simulator without real devices

D. Skip testing and rely on user reviews after release

Solution

1. Step 1: Identify iOS testing tools

   TestFlight is Apple's official tool to distribute pre-release apps to testers.

2. Step 2: Evaluate other options

   Uploading without testing or skipping testing risks app failure; simulator-only testing misses real device issues.

3. Final Answer:

   Use TestFlight to distribute the app to testers -> Option A

4. Quick Check:

   iOS pre-release testing = TestFlight [OK]

Hint: Use TestFlight for iOS pre-release testing [OK]

Common Mistakes:

• Skipping real device testing
• Uploading without testing
• Relying only on simulator tests

3. Consider this Android app testing code snippet using Google Play testing tracks:

val testTrack = "internal"
val appVersion = 5
if (appVersion >= 5) {
  println("App ready for $testTrack track testing")
} else {
  println("App version too low for $testTrack track")
}

What will be printed when this code runs?

medium

A. App version too low for internal track

B. App ready for alpha track testing

C. App ready for internal track testing

D. Compilation error due to syntax

Solution

1. Step 1: Check the appVersion value

   appVersion is 5, which is equal to the condition threshold (>= 5).

2. Step 2: Evaluate the if condition

   Since 5 >= 5 is true, the first println runs, printing "App ready for internal track testing".

3. Final Answer:

   App ready for internal track testing -> Option C

4. Quick Check:

   appVersion 5 meets condition, prints ready message [OK]

Hint: Check if condition true to find printed message [OK]

Common Mistakes:

• Misreading the >= operator
• Confusing track names
• Assuming syntax error without checking code

4. You wrote this snippet to test app submission readiness:

if (appInfo.isComplete = true) {
  println("Ready to submit")
} else {
  println("Incomplete app info")
}

What is the error in this code?

medium

A. No error; code runs correctly

B. Missing semicolon at the end of println statements

C. Incorrect method name; should be isCompleteInfo()

D. Using assignment (=) instead of comparison (==) in the if condition

Solution

1. Step 1: Identify the if condition syntax

   The condition uses single = which assigns true instead of comparing.

2. Step 2: Understand correct comparison

   To check equality, use == instead of = in conditions.

3. Final Answer:

   Using assignment (=) instead of comparison (==) in the if condition -> Option D

4. Quick Check:

   Use == for comparison, not = [OK]

Hint: Use == for comparison in if conditions [OK]

Common Mistakes:

• Confusing = and == in conditions
• Assuming semicolons are mandatory in Kotlin/Swift
• Thinking method name is wrong without context

5. You want to test your app on multiple devices before submission. Which approach best ensures thorough testing and smooth app store approval?

hard

A. Rely solely on automated tests without manual device testing

B. Use real devices with different OS versions and TestFlight or Google Play testing tracks

C. Test only on the newest device model and skip beta testing

D. Submit the app immediately and fix issues after release

Solution

1. Step 1: Identify best testing practices

   Testing on real devices with various OS versions catches more issues and matches real user environments.

2. Step 2: Use platform beta testing tools

   TestFlight (iOS) and Google Play testing tracks allow controlled distribution and feedback before public release.

3. Final Answer:

   Use real devices with different OS versions and TestFlight or Google Play testing tracks -> Option B

4. Quick Check:

   Real devices + beta tracks = thorough testing [OK]

Hint: Combine real devices and beta tracks for best testing [OK]

Common Mistakes:

• Testing only on newest device misses compatibility issues
• Skipping manual testing reduces issue detection
• Ignoring beta testing risks app rejection
