    TESTING EXERCISE VOLCONTROL

    This is what kept James Bach out of Test Lab at Lets Test 2013.

    It takes at least 90 minutes, but feel free to take your time, depending on how deep you want

    to go.

    If you have any questionsfeel free to send me an email (info-at-

    testerstower.com) , find me on Skype(ID: kristjan.uba), tweet(@kristjanuba) or

    leave a comment here.

    Find the exercise description below:

    Extract the RAR for the console and rename it to .exe. Use the Excel Worksheet to do record

    your tests results and bug reports

    Context:

    Product under test is a television with the possibility of connecting to a mobile device (for

    example, to play videos from Youtube or Netflix). When playing video the mobile device should

    be able to control the volume of the television. The scope of your testing is the Volume Control

    software module (inside the television), isolated into the test console, so the focus of testing is

    only the internal logic of that component.

    Assignment:

    Analyze the component specification and create an artifact to show necessary combinations to

    cover this component. Also, note the bugs in the component. The component can be controlled

    via the test console. The test console will produce a log of your actions.

    Exercise outputs:

    At the end of the exercise I expect from you:

    * A small document/picture/mind map that shows what kind of combinations need to tested.

    This doesnt need to be fully detailed, butclear enough to communicate test coverage to

    developers and testers;

    a. List of bugs found

    b. The log(s) from the test console

    Note! To get the log files the test console must be

    exited with exit.

    Closing from the window with x will not work.

    Volume Control component specifications v2:

    The software module controls the volume of the TV according to user actions.

    User can increase/decrease the volume, mute on TV or via mobile device.

    The component must handle volume handling when mobile device is connected.

    The goal is to minimize the situation when using mobile device creates big

    increases in TV volume.

    Requirements:

    * TV Volume can be increased or decreased in 2 steps, in range of 0..90

    * Increasing/decreasing volume via TV also demutes

    * Mute command toggles mute on/off

    * Mobile device volume can be increased or decreased in 1 steps, in range of 0..20

    * Mobile device cannot increase TV volume over the current TV volume value when connected

    * Connecting mobile device must set the current volume level according to mobile device

    * Disconnecting mobile device must restore the volume to a level that was before connecting

    - When volume was changed via TV while connected that new value must be respected

    * Demuting volume over 70, must set volume to 70 first

    For example:

    * #1:

    TV vol is set to 20. Connecting mobile device with max volume,

    then every step down on mobile device the TV volume will be decreased by 1 step.

    * #2:

    TV vol is set to 40. Connecting mobile device with volume set to 10,

    then TV volume will be set to 20, and increasing the volume to maximum on mobile device will

    increase the TV back to 40.

    * #3:

    TV vol is set to 20. Connecting mobile device with volume set to 10,

    then TV volume will be set to 10. Increasing TV volume 5 times, will put the TV volume to 15

    and

    after disconnecting set the TV volume to 30.
