Every time testers accept a cycle, a routine should be followed to minimize mistakes while reporting problems and avoid issues at their end. In this article, we’ll show you some of the mandatory actions that should be included in your own routine that’ll help you avoid requests and rejections from our Team Leaders in the future.

General tips

  • The first thing we recommend is to make sure your device has enough battery and is not running on any power-saving mode that could affect its performance.

  • Before your start recording, make sure that your screencast software is set to record in .mp4 format and codec H.264. If you cannot see which codec and file format your screen recording software is using, we recommend using Screencast-O-Matic.

  • When you make a recording, the frame rate must be high enough to identify your actions and to analyze the course of events.

  • You should always test in a quiet and reserved place. You are not authorized to share customer information with other people that are not part of the test cycle or a recognized Test IO employee. That also means sharing data with relatives, friends or even other testers that are not part of the cycle is strictly forbidden.

  • Cabled internet will usually produce better results than a Wi-Fi connection. Also, the 5GHz connection (if you have it available) it’s also faster and more reliable. If you have a portable device (a notebook, a phone or a tablet), it’s a good option to stay as close as possible to your Wireless access point to avoid network issues.

  • You must close all apps and tabs that are not useful to understand the issue. Notifications from other apps can also be muted to avoid interruptions while recording a bug. When you take an app to test, you must be focused on the app at all times and pay attention to everything that’s happening on your screen, so it’s easier to do that if any content that might distract you is disabled.

  • When testing websites, it’s a good idea to close all irrelevant tabs on your browser to make sure your device won’t suffer from high Random Access Memory (RAM) usage.

  • It’s recommended to take an internet speed test at the beginning of the test session to make sure your internet speed is fast and stable enough to not cause unexpected behaviours. For that, you can use websites such as or

  • Your device and/or browser language should be set to either English or German for exploratory cycles, depending on the language accepted in the cycle instructions. This way all errors and relevant messages will be shown in the correct language. However, for Localization testing, you must set the language to one that you are familiar with and is part of the list requested by the customer. Keep in mind customers might ask you to change the device location and languages to other ones too, even on exploratory cycles, but such information will be explicit on the test cycle instructions or will be passed by the TL or CSM through the cycle Chat.

Testing on a Desktop device

For a desktop device, you will usually not need to change any major settings (unless you’re running a really customized OS). Our recommendations are:

  1. Make sure the screen resolution is set to the device's default one and the text/image scale is set to 100%. Your browser zoom must also be at 100%. This will make sure you are seeing the websites and apps under the correct resolution intended by the customer.

    1. For Windows devices, you must navigate to “Start > Settings > System > Display”, and make sure the “Display Resolution” is set to the native recommended value and the “Scale and layout” is set to 100%.

    2. For Mac OS, choose “Apple menu > System Preferences > Displays > Display Settings” and select your display in the sidebar. Then select Display and set the Resolution to the “Default for display” option.

  2. You must have at least one common browser (Google Chrome, Safari, Microsoft Edge and Firefox are the most requested ones by our customers) and one screen recording tool. Since you are required to show the mouse clicks on desktop devices, you might need to install an extra third app tool for that. Some screen recording tools (such as Screencast-O-Matic or Bandicam) can highlight the mouse actions without needing any extra app. Please refer to our Screencasts article for more information. You must also get familiar with how to take Screenshots on your Desktop device.

    1. For Windows devices, we recommend you use the Snipping Tool to capture the screenshot of the screen you want to share. You can access it by searching for “Snipping Tool” on the Windows search or using the keyboard shortcut Windows Key + Shift + S. Your screen will be greyed out and you will be able to select the area you want to take the screenshot. A notification will be shown after you’ve taken the screenshot and you can click on it to go to the editor tool.

    2. For Mac OS, you can open the Screenshot app by using the shortcut “Shift + Command + 5”. You can then select the type of screen capture you want (the entire screen or part of it) and take your Screenshot. You will be prompted to save the picture and you can then select the proper folder to save it.

  3. Before starting the test session, make sure your browser settings are all set to default and you’re not running any extensions that change the page behaviour (such as translators or ad/script blockers). We recommend you install multiple browsers and use one as your default personal web navigation and all others for testing purposes only.

  4. Resizing the browser might cause the page to show in tablet or phone mode (which is considered a forced behaviour), so it’s best to always leave your browser covering your entire screen (resized to its maximum resolution) to avoid unexpected results.

  5. You must also make sure your screen recording app settings are correct. Remember your screencast quality must be good enough to understand your issue and you must always record the entire browser/app page. So, make sure the screencast resolution and framerate are high enough to be watched on most modern devices with no issues or frame drops.

  6. Windows and mac OS will already show the current date and time by default if you’re not using any full-screen app. In case you’ve changed this default option and don’t know how to change it back:

    1. For Windows, navigate to “Start > Settings > Time & language > Date & time” and select “Region”

Testing on an Android Mobile or Tablet device

For Android devices, you will need to complete a few steps before start testing our customer’s apps. Depending on the Android version and the maker of your device, the options might be located in different settings. Please make yourself familiar with these settings on your device and if you have any questions, you can ask for our support help or find anyone with a similar device in our Discord Community server to help you set up yours.

  1. On Android 11+, you might not need to install any third-party app to record your screen in case your device already has an integrated recording tool available on your notification bar. However, if your device is running Android 10 or less or if it does not have a built-in recording tool, you will need to install a third-party app to record your screen. Please refer to our Screencasts article for more information.

  2. To take Screenshots, you will need to learn what is your device shortcut for this action and if you must quickly press the buttons or hold them. The default shortcut options are usually by pressing the Power + Volume Down buttons or Power + Home.

  3. You will also need to enable the option to show touches by unhiding the Developer options menu. To do that, you must navigate to the device Settings and select the About device or About phone option. Then under the Software information, you must tap on the Build Number option 7 times. The “Developer options” menu will be unlocked and will be accessible on your device Settings. Finally, you can navigate to this menu and enable the “Show taps” option. You can find more information on this website here.

  4. To capture logs using a desktop computer, you must enable the USB debugging option under the “Developer options” menu. To do that, you can follow the previous topic here to enable the dev options and simply toggle on the USB debugging option. Since device logs are mandatory when reporting Crash bugs, we recommend you keep this option enabled while testing. More tools and information about how to capture Android crash logs can be found in this article here from our Academy.

  5. The customer will usually provide you with a file with the extension .apk to install on your device. If it’s your first time installing an app from a source outside the Google Play Store, your device might block you from doing that for security reasons. If that happens to you, please navigate to the Settings menu and search for the “Install unknown apps” option. You must grant permission to the correct app source of the .apk file you want to install (it’s usually the browser or any file manager app on your device).

  6. The customer might also share the app via Firebase with you, which is an App Distribution platform provided by Google to help developers to distribute staging/beta apps for testing purposes. You will need a Gmail account to accept the invites. We also recommend you install the App Tester app to make it easier for you to access the builds list. You can get it on this link here (you must access it using an Android device).

Testing on an iOS or an iPad device

For Apple mobile and tablet devices, you are not required to install any third-party app since there’s a built-in recording tool in all relevant devices for our customers today, which will be running iOS 11 or newer. You are also not required to show the touches/taps on these devices, although it is possible using the “AssistiveTouch” option.

  1. To take screenshots, you need to use the shortcut Power + Home buttons for devices with a physical Home button or Power + Volume Up buttons for devices that don’t have a physical Home button.

  2. For screencasts, you must navigate to “Settings > Control Center” and tap on the green plus button next to Screen Recording to enable this option. The option will be added to your Control Center, which can be accessed by swiping up or down close to the vertical limits of the screen depending on your device. Now you can start the recording and the video will be saved to your device. Remember to mute your phone audio while recording to avoid capturing the sound, unless it is required to understand the bug.

  3. The customer will usually provide you with a link to install the app directly on your device. Upon downloading it, you will need to navigate to “Settings > General > Profiles or Profiles & Device Management” and under the Enterprise App, tap on the customer’s name or test IO GmbH option. Finally, you must trust this developer to unlock the app.

  4. The customer might also share the app via Testflight with you, which is an app distribution platform provided by Apple to help developers to distribute staging/beta apps for testing purposes. You will need an Apple ID account to accept the invites and to download the apps. You will also need the Testflight app installed on your device to access it. Keep in mind the app is only available for iOS 13 or later. You can get it on this link here (you must access it using an iOS device).

  5. To capture logs using a desktop computer, you must have the correct drivers which can be obtained by installing the iTunes desktop app and then connecting your iOS device via a USB cable. More tools and information about how to capture iOS crash logs can be found in this article here from our Academy.
