The Fibonacci sequence (Fibonacci sequence), which was introduced by the mathematician Leonardo's Fibonacci (Leonardoda Fibonacci) as an example of rabbit reproduction, is also known as the "rabbit sequence", and because its two adjacent items are infinitely closer to the golden ratio, So also known as the Golden section of the series, refers to a number of such a series: 1, 1, 2, 3, 5, 8, 13, 21, the 、....

Haha, because in the course of online teaching found a lot of small partners actually told once, actually still can't fix, so increased.First we need to take care of an environment, here, whether it is appium, or selenium or other automation, development environment we can follow this idea, first you need to know what the framework is to do? Then his whole workflow or the whole framework of his dependencies on the software is what. It doesn't matter here, we look back at the
