The unittest<\/a><\/code> module is part of Python’s standard library for a long time. So in most cases, there’s no need to install it using something like pip install unittest<\/code>. Simply run import unittest<\/code> in your Python code and it works without installation.<\/p>\n

In your Python code:<\/p>\n

import unittest<\/pre>\n
If you try to pip install<\/code> it, you’ll get the following error Could not find a version that satisfies the requirement unittest<\/code> that you can fix by not installing it in the first place (it already is)!<\/p>\n
PS C:\\Users\\xcent> pip install unittest\nERROR: Could not find a version that satisfies the requirement unittest (from versions: none)\nERROR: No matching distribution found for unittest<\/pre>\n
\"\ud83d\udc49\" Recommended Tutorial<\/strong>: How to Check ‘unittest<\/code>‘ Package Version in Python?<\/a><\/p>\n
Feel free to also check out our full guide on the PyTest framework<\/a> which is great for testing purposes too!<\/p>\n
Python 2 Backport UnitTest2<\/h2>\n
If you’re using Python 2, you can try installing the unittest2<\/a><\/code> package that is a backport for unit testing in Python 2.7. Then <\/p>\n
pip install unittest2<\/pre>\n
Then add the following line to your Python code instead of import unittest<\/code>:<\/p>\n
import unittest2<\/pre>\n
Legacy Solutions to Install UnitTest Module<\/h2>\n
For some very old Python versions, you may want to try this approach:<\/p>\n
Quick Fix:<\/strong> Python raises the ImportError: No module named 'unittest'<\/code> when it cannot find the library unittest<\/code>. The most frequent source of this error is that you haven’t installed unittest<\/code> explicitly with pip install unittest<\/code>. Alternatively, you may have different Python versions<\/a> on your computer, and unittest<\/code> is not installed for the particular version you’re using.<\/p>\n
To fix this error, you can run the following command in your Windows shell:<\/p>\n
$ pip install unittest<\/pre>\n
This simple command installs unittest<\/code> in your virtual environment on Windows, Linux, and MacOS. It assumes that your pip<\/code> version is updated. If it isn’t, use the following two commands in your terminal, command line, or shell (there’s no harm in doing it anyways):<\/p>\n
$ python -m pip install – upgrade pip\n$ pip install pandas<\/pre>\n
\"\ud83d\udca1\" Note<\/strong>: Don’t copy and paste the $<\/code> symbol. This is just to illustrate that you run it in your shell\/terminal\/command line. <\/p>\n
The error might persist even after you have installed the unittest<\/code> library. This likely happens because pip<\/code> is installed but doesn’t reside in the path you can use. Although pip<\/code> may be installed on your system the script is unable to locate it. Therefore, it is unable to install the library using pip<\/code> in the correct path.<\/p>\n
To fix the problem with the path in Windows follow the steps given next. <\/p>\n
Step 1<\/strong>: Open the folder where you installed Python by opening the command prompt and typing where python<\/code><\/p>\n
\"\"<\/figure>\n
Step 2<\/strong>: Once you have opened the Python<\/code> folder, browse and open the Scripts<\/code> folder and copy its location. Also verify that the folder contains the pip<\/code> file.<\/p>\n
\n
\"\"<\/figure>\n<\/div>\n
Step 3<\/strong>: Now open the Scripts<\/code> directory in the command prompt using the cd<\/code> command and the location that you copied previously. <\/p>\n
\n
\"\"<\/figure>\n<\/div>\n
Step 4<\/strong>: Now install the library using pip install unittest<\/code> command. Here’s an analogous example:<\/p>\n
\n
\"\"<\/figure>\n<\/div>\n
After having followed the above steps, execute our script once again. And you should get the desired output.<\/p>\n
