J2EE tester 測(cè)試器是一款用于測(cè)試發(fā)布于服務(wù)器端（如Weblogic, Websphere）的 EJB組件、Servlet以及 Beans的黑盒/白盒智能化測(cè)試工具。它的功能主要有以下三點(diǎn)： 1. 自動(dòng)生成被測(cè)試類的覆蓋度測(cè)試報(bào)告，生成相應(yīng)的dmp文件。 2. 自動(dòng)生成被測(cè)試類的出錯(cuò)報(bào)告，記錄拋錯(cuò)的行數(shù)，出錯(cuò)類型,方法名稱，時(shí)間以及該行的代碼。 3. 按照需要在發(fā)生錯(cuò)誤的行產(chǎn)生斷點(diǎn)，讓測(cè)試者查看此時(shí)各個(gè)變量的狀態(tài)。

利用單片機(jī)具有的智能程序控制的特點(diǎn)，設(shè)計(jì)了基于STC89C52單片機(jī)的"二極管特性測(cè)試器"，可對(duì)二極管一般特性進(jìn)行快速測(cè)試。通過(guò)穩(wěn)定線性電流源給二極管加載恒定電流，然后由高精度模數(shù)轉(zhuǎn)換器測(cè)試其壓降，以此為基礎(chǔ)可判斷二極管好壞、檢測(cè)二極管極性和測(cè)試二極管伏安特性等，避免了用萬(wàn)用表測(cè)試只能測(cè)得極性而不知其特性這一缺點(diǎn)。可用于電子設(shè)計(jì)制作過(guò)程中對(duì)二極管進(jìn)行快速測(cè)試，以確定被測(cè)二極管是否滿足電路的設(shè)計(jì)要求。 Abstract: By making good use of the intelligent control function of the Micro Controller Unit (MCU)， the diode trait tester was designed based on the STC89C52，which could be used to test the trait of a diode rapidly. By loading constant current to diode through the stable linear current source， and measuring the voltage drop of the diode by high-precision analogue-to-digital converter (ADC)， it can judge whether the diode is good or not， distinguish the polarity of the diode， and test the trait that the diode， which can avoid the fault of using a multimeter can only measure the polarity but not the trait. This device can be used to test the trait of a diode quickly，and to make sure that whether a diode can be used in the electronic design or not.

Designing Boards with Atmel AT89C51,AT89C52, AT89C1051, and AT89C2051 for Writing Flash at In-Circuit Test. Recent improvements in chips and testers have made it possible for the tester to begin taking over the role tradi-tionally assigned to the PROM program-mer. Instead of having a PROM pro- grammer write nonvolatile memories before assembling the board, the in-cir- cuit tester writes them during in-circuit testing operations. Many Teradyne Z18- series testers are now in use loading code into nonvolatile memories, micro- controllers and in-circuit programmable logic devices. The purpose of this note is to explain how the Z18 approaches the writing task for Atmel AT89C series IC’s, so that designers of boards using these chips can get the best results.
