Disadvantages of Test Driven Development? [closed]

Several downsides (and I'm not claiming there are no benefits - especially when writing the foundation of a project - it'd save a lot of time at the end):
Big time investment. For the simple case you lose about 20% of the actual implementation, but for complicated cases you lose much more.

Any change you make to the contents of this object will be seen identically whether you reference it through the a variable or the b variable. They are the same object.
So, when you later try to "revert" b to the original a object with this code:
b = a;
The code actually does nothing at all,...
How to create a memory leak in Java?
...a thread pool to leak even faster).
The thread loads a class via an (optionally custom) ClassLoader.
The class allocates a large chunk of memory (e.g. new byte[1000000]), stores a strong reference to it in a static field, and then stores a reference to itself in a ThreadLocal. Allocating the extra ...
How to add an empty column to a dataframe?
... with .reindex(rows=[...]). Note that newer versions of Pandas (v>0.20) allow you to specify an axis keyword rather than explicitly assigning to columns or rows.
Here is an example adding multiple columns:
