soapUI Pro指标项说明：
Test Step
Sets the startup delay for each thread (in milliseconds)， setting to 0 will start all threads simultaneously.
min
The shortest time the step has taken (in milliseconds).
max
The longest time the step has taken (in milliseconds).
avg
The average time for the test step (in milliseconds).
last
The last time for the test step (in milliseconds).
cnt
The number of times the test step has been executed.
tps
The number of transactions per second for the test step， see Calculation of TPS/BPS below.
bytes
The number of bytes processed by the test step.
bps
The bytes per second processed by the test step.
err
The number of assertion errors for the test step.
rat
Failed requests ratio (the percentage of requests that failed).
　　1、Test Step：调用方法名称。
　　2、min、max、avg、last：调用时的小、大、平均、近一次的响应时间
　　3、cnt总调用次数 ；tps平均每秒调用次数
　　4、bytes接口处理的字符数；bps平均每秒接口处理的字符数
　　5、err报错次数；rat报错次数/执行次数
　　或
　　min，小响应时间
　　max，大响应时间
　　avg，平均响应时间
　　last，上一次请求响应时间
　　cnt，请求数
　　tps，每秒处理请求数
　　bps，吞吐率
　　rat，错误率
