Summary
In this chapter, we have seen code for testing the speed of an iSAX index and joining two iSAX indexes based on the SAX representations of their nodes. Then, we briefly discussed the subject of testing Python code and implemented three tests for the isax package.
We also discussed the joining of iSAX indexes, which is based on the node types. Additionally, the tests we carried out made sure that the core logic of our code is correct.
In the next chapter, we are going to learn how to visualize iSAX indexes to better understand their structure and performance.
Before you start reading and working through Chapter 6, experiment with the command-line utilities that we have developed in this chapter and try to create your own.
