LoadRunner檢查點(diǎn)使用小結(jié)

1、LoadRunner檢查點(diǎn)使用小結(jié)LR中檢查點(diǎn)有兩種：圖片和文字。這兩種檢查點(diǎn)可用以下三個(gè)函數(shù)實(shí)現(xiàn)：web_find()、web_reg_find()和web_image_check()下面分別介紹三種函數(shù)的用法1、web_find()函數(shù)函數(shù)作用：在頁面中查找相應(yīng)的內(nèi)容參數(shù)舉例：web_find("web_find","RighOf=a","LeftOf=b","What=name",LAST);參數(shù)解釋："web_find"定義該查找函數(shù)的名稱；“LeftOf”和“RighOf=”用來定義查

2、找字符的左右邊界；“What=”定義查找內(nèi)容。例如上述參數(shù)舉例中的意思就是在頁面中查找左邊界為b，右邊界為a，內(nèi)容為name的信息函數(shù)用法：該函數(shù)是在查找頁面中的內(nèi)容，所以要放在要查找的內(nèi)容的后面。注意事項(xiàng)：使用該函數(shù)時(shí)，要在Vuser->Run-Tme Settings中更改下設(shè)置勾選Enable Image and text check系統(tǒng)默認(rèn)是不勾選該選項(xiàng)的。2、web_reg_find()函數(shù)函數(shù)作用：在緩存中查找相應(yīng)的內(nèi)容參數(shù)舉例：web_reg_find("Search=Body","SaveCount=ddd","Test=

3、aaa",LAST);參數(shù)解釋： Search用來定義查找范圍，SaveCount定義查找計(jì)數(shù)變量名稱，該參數(shù)可以記錄在緩存中查找內(nèi)容出現(xiàn)的次數(shù)，可以使用該值，來判斷要查找的內(nèi)容是否被找到例如上述參數(shù)舉例中的意思就是Body中查找內(nèi)容為aaa的信息，并將出現(xiàn)次數(shù)記錄在變量ddd中。函數(shù)用法：該函數(shù)是在緩存中查找相應(yīng)的內(nèi)容，所以要放在查找內(nèi)容之前。注：在錄制過程中添加的檢查點(diǎn)，用到的函數(shù)是web_reg_find()，且參數(shù)只有“Text=”3、web_image_check()函數(shù)函數(shù)作用：在頁面中查找一個(gè)具體的圖片。參數(shù)說明：web_image_check("web_im

4、age_check","Alt=","Src=",LAST);參數(shù)解釋：“Alt”和“Src”的值直接取該圖片在網(wǎng)頁源代碼中相應(yīng)參數(shù)的值。函數(shù)用法：該函數(shù)是在緩存中查找相應(yīng)的內(nèi)容，所以要放在查找內(nèi)容之前。注意事項(xiàng)：使用該函數(shù)時(shí)，要在Vuser->Run-Tme Settings中勾選Enable Image and text check，具體操作請(qǐng)看web_find()中的注意事項(xiàng)。經(jīng)過測(cè)試，該函數(shù)用到查找內(nèi)容前面或后面，都不影響查找結(jié)果。舉例說明（腳本）該腳本記錄的是登陸系統(tǒng)后退出的操作，在腳本中用到atoi()函數(shù)和lr_eval_s

5、tring(”SaveCount定義的變量”)兩個(gè)函數(shù)結(jié)合使用，判斷查找內(nèi)容出現(xiàn)的次數(shù)是否大于0，若大于0，則輸入登錄成功的信息。vuser_init()web_url("xjcost","URL=http:/gczj-server8:9205/xjcost/","Resource=0","RecContentType=text/html","Referer=","Snapshot=t1.inf","Mode=HTML",EXTRARES,"Ur

11、輸出“Log on successfully!”if(atoi(lr_eval_string("歡迎您_Count")>0)lr_output_message("Log on successfully!");elselr_error_message("Log on failed!");return 0;return 0;/atoi()函數(shù)的作用是將一個(gè)ASCII字符串轉(zhuǎn)換為整型/lr_eval_string()函數(shù)作用是取得參數(shù)值，將字符串變量中的參數(shù)值替換為當(dāng)前的參數(shù)值并將這個(gè)字符串返回vuser_end()lr_think_
