LoadRunner如何计算事物成功率

LoadRunner如何计算事物成功率

事务的成功或失败是可以人为控制的，在做性能测试的时候，录制完脚本后，需要对脚本进行优化，其中优化的一部分就添加判断事务成功失败的条件。例如（判断登录是否成功）：
lr_start_transaction("log");
web_edit_field("username",
"Snapshot=t1.inf",
DESCRIPTION,
"Type=password",
"Name=username",
ACTION,
"SetEncryptedValue=4e02cb503ed6421aa162a0ef036586beb979",
LAST);
web_edit_field("password",
"Snapshot=t2.inf",
DESCRIPTION,
"Type=password",
"Name=password",
ACTION,
"SetEncryptedValue=4e02cb521a637d3b",
LAST);
//if log successfully,"Account Summary" will display
web_reg_find("Text=Account Summary","SaveCount=count1",LAST);
web_button("INPUT",
"Snapshot=t3.inf",
DESCRIPTION,
"Type=submit",
"Tag=INPUT",
"ID=",
ACTION,
"UserAction=Click",
LAST);
if (atoi(lr_eval_string("{count1}"))==1)
{
lr_end_transaction("log", LR_PASS);
lr_output_message("log suss,because %d", atoi(lr_eval_string("{count1}")));
}
else
{
lr_end_transaction("log", LR_FAIL);
lr_error_message("log failed,because %d", atoi(lr_eval_string("{count1}")));
}
