how to write junit test

The first line of code: ethereum began to be serialized. In this article, we have used the remix environment to run and test the first smart contract program written in this book. However, there are many testing methods for writing and testing smart contracts, for example, testing in the testrpc environment; in intellij idea integrated development environment, you can use the solidity language to write sma

FIO is an I/O tool that can be used for benchmarking and hardware stress testing. It supports 19 I/O engines (sync, mmap, Libaio, Posixaio, SG v3, splice, NULL, network, Syslet, Guasi, Solarisaio, etc.), supporting block devices and files. Support for Linux, FreeBSD, NetBSD, OpenBSD, OS X, Android, Windows, OpenSolaris, AIX, HP-UXhttp://freecode.com/projects/fio/ FIO Usage1. Random Reading and writing:Fio-filename=/tmp/test-direct=1-iodepth 1-thread-r

DD is a very useful command under Linux/unix, which is used to test the sequential read-write capability of a hard disk by copying a file with a specified size and making the specified conversion at the same time as the copy. Can write files, can write bare devices. DD syntax Function Description: Read, transform and

Time is used for timing. dd is used for copying, reading from if, and writing to. If =/dev/zero does not produce IO, so it can be used to test the pure write speed. Similarly, of =/dev/null does not generate IO and can be used to test the pure read speed. Bs indicates the size of each read or write, that is, the size o

* this.bmpData.Stride)) + (x * 3));11 return Color.FromArgb(numPtr2[2], numPtr2[1], numPtr2[0]);12 }13 return Color.Empty;14 } Because I am relatively idle, I am wondering how fast is the acceleration? To this end, I slightly adjusted the bitmapex class I used previously (remember whether it should be facial recognition or code), changed it to fastbitmap, and then created a test program, A series of

lines in our code, they are the default.ZTest, depth test; lequal, less than equals.Zwrite, depth write, on, open.ZTest values are: Greater, gequal, less, lequal, Equal, notequal, always, never, off, by default lequal,ztest off equals ZTest alway SThe Zwrite value is: On, OFF, default is on.There is a color buffer and a depth buffer in the system that stores the color values and depth values to determine w

Test the read/write performance of the volatile variable. Test the Read and Write Performance of the volatile variable. The difference between the volatile variable and the non-volatile variable is that each read of the volatile variable needs to read the latest value from the primary memory, and each

In the company to do stress testing also quite a long time, every test before the environment data preparation need to spend a long time, so has been considering the whole process can be automated, so the time to write an automated script, of course, the script is very primitive, the code is not perfect, there are many need to change the place, Subsequent re-optimization. If there is any mistake or improper

http://blog.csdn.net/killmice/article/details/42745937 The test tool FIO is read sequentially as an example, with the following commands: fio-name IOPS-RW = Read-bs = 4k-runtime = 60-iodepth 32-filename/dev/sda6-ioengin E Libaio-direct = 1 where rw = read for random reads, BS = 4k for each read 4k, filename specifies the corresponding partition, here I am/dev/sda6, direct = 1 means the cache through Linux Test
