It might seem like a bit much, but one thing I can think of is to use a virtual machine, and set its virtual disk to just big enough to fit the OS on. Fill it with some garbage files to tip it over the edge, then run your program.

Best thing that works on every computer (as testing is not neceessarily done on a dedicated machine) would be a ramdrive/ramdisk that could be set up on the fly.

Only found a Virtual Disk SDK so far <a href="http://eterlogic.com/Products.VirtualDriveSDK.html" rel="nofollow noreferrer">see here</a> that maybe could be included in your buzild process.

Different idea: maybe your testing computers could be set up to write to a shared network folder (that is full) mount as a drive?

For Windows XP or later:

This command can get the amount of free space for the c:\ drive:

<pre><code>for /f "usebackq tokens=1-5" %%A in (`dir c:\ ^| find "bytes free"`) do (
 set FREE_SPACE=%%C
)
</code></pre>

Replace c:\ with your drive, as needed.

You can then take some space away from this value so you have a little room to work with:

<pre><code>set /a FREE_SPACE=FREE_SPACE-1024
</code></pre>

or however much space you want to keep free.

You can use the <code>fsutil</code> command to create a file to fill up the free space on the disk:

<pre><code>fsutil file createnew c:\spacehog.dat %FREE_SPACE%
</code></pre>

Run your test, writing to the drive. After you write 1024 bytes or so you should run out of space.

I have made a modification to the above script to make it compatiable with Windows 7... Essentially adding the switch "/-c" to the for statement. This removes the thousands seperator as fsutil does not like it in the statement.

I have to write a bat script for a test scenario where the software that we are testing fails to write to file due to a disk full error. The test script must be automated, so that we can run it on overnight tests, for example. The test script must also work at different computers, so installing a software like a virtual machine wouldn't be the best solution in this case.

How can I simulate that error in a Windows environment?

How can I simulate a disk full error in a Windows environment?

虚拟机

Windows

我必须为我们正在测试的软件由于磁盘已满错误而无法写入文件的测试场景编写一个bat脚本。例如，测试脚本必须是自动化的，这样我们就可以在夜间测试中运行它。测试脚本还必须在不同的计算机上运行，因此安装虚拟机之类的软件在这种情况下不是最好的解决方案。如何在Windows环境中模拟该错误？
