Software.
It's not like engineering something easy like a bridge, where you start with a blueprint, build it to spec, then forget about it.
Software is dynamic with a lot of moving moving parts and requirements that evolve over time.
Developers build apps on top of a mountain of abstractions, and nobody fully understands how every layer works.
That's okay because we just need to make sure that our code matches the requirements of the product.
Test driven development is scientifically proven to reduce defects and improve the maintainability of a code base, but it does require some additional effort.
One option is manual testing where a human being clicks on every button and fills out every form, then assigns a bunch of Jira tickets so they can be backlogged by the developers, but that's not very efficient for a large scale product.
A better approach is to use automated testing tools that allow developers to write code for the sole purpose of testing the main application code.
In a code base, you'll often find files that end in dot test to or dot spec.
Inside, you'll first find a line of code that describes the feature or thing that's being tested.
That's known as a test suite and it contains 1 or more individual tests.
An individual test usually starts with it followed by a description of what is being tested.
The idea is to describe the behavior of the code and human readable terms.
Inside the test, the code will be executed, then 1 or more expectations or assertions are used to check that the code produces the expected result.
If the expectation returns false, then the test fails.
If it's true, it passes.
Test runners like Jest or Karma can run all your tests automatically in the background or on a continuous integration server before you deploy.
Now there are many different move made testing strategies that you should be aware of.
At the most granular level, we have unit testing, which is designed to test individual functions or methods.
Like, does this function return the proper value when given the arguments of a and b.
Then we have integration testing to determine how well different components or modules work together, like is the component able to use the database service to to get data from the server.
At the highest level, we have end to end testing, which usually happens in a mock browser or device and simulates actual user behaviors like clicking on buttons and filling out forms.
It's like having a robot to do all your manual testing for you.
And that's not all.
There are many other types like performance and smoke testing, which I'll explain in my upcoming test driven development breakdown.

The speaker explains that software development is like building a bridge, where the developers build apps based on a maturation of technical requirements. The process involves manual testing, automation, and end-to-end testing, including performance and smoke testing. Different tests can be conducted, including unit testing, integration testing, and end-to-end testing, and there are many different ways to test.
Software Testing Explained in 100 Seconds
When you develop software, it's a good idea to make sure it works by testing it. Test-Driven Development (TDD) can help you understand your code and decrease bugs. https://fireship.io/tags/testing/
