regression testing falls under white box or black box testing?

Answer Posted / suraj khabale

Regression testing is testing of the unchanged part. since Changed part is tested and impact of it need to be measured on unchanged part. IN this case whitebox is practically not possible because Going through unchanged code (Obviously it is going to be huge) is rework of whitebox which is vast stage of testing. so possibly by having impact analysis we can do Blackbox testing on LInked modules of Changed module.

1.1 Purpose This tool is also a simple tool, but will be graphics- intensive, and will access the 3 databases (card databases) used in Tarot. 1.2 Scope Only for registered user. 1.3 User Interface - No questions asked, parrot pulls out tarot card - Inside Parrot application, User just have to click on a link saying ""XXXX"" to activate the tool. - Shown is the card of the day, from pack of Tarot cards(78 in number) with fixed graphics, animation, audio. Output: - Graphic-rich display of randomly selected card with detailed meaning, with links to tarot tool. - Graphics: Flying / walking parrot, emerging and choosing a card, displaying the same, and continuing to interact based on card meaning. - The cards also need to carry a brief 1/0 meaning, which will trigger a 1/0 behavior from the parrot (sympathy/making fun/crying or congratulating/smiling/winking)

1 Tarot 1.1 Purpose - Tarot tool will duplicate the tarot-reading process for the user online. - Tarot is a craft that uses a deck of 78 cards to predict a user’s past, present and future. - The cards are picked by the user and arranged in a specific spread, which represents points in his past, present, and future; based on the meanings of the cards selected, interpretations are given. 1.2 Scope Only for registered user. 1.3 User Interface User Interface: 1. Question – This is only for user experience, and has no bearing on the formulae / process. Simple long text box. 2. Selection of field – radio button selection of 1 of 3 choices(Love, Career, Personal), which affects 1 of 3 card- meaning databases to be used. After selection, the unselected databases do not affect or interact with the system. 3. Spread Selection – radio button selection of 1 of 3 choices(Celtic Cross, Horse Shoe, Simple 3 Card). This determines the number of cards being picked and the specific spread database to be used. This also affects the specific report format being used, as well as the card- selection GUI. 4. Card Selection – based on the input 3, a specific layout is shown where the user needs to identify X number of cards (X also determined by input 3) which are then shown in the spread. Every card selection identifies the spread position constants (A, B, C, etc) with specific variable values (Card numbers) creating an array. Report format will display on a separate new page, in the following sequence – - Statement of question asked - Selection of field - Selection of spread - Detailed description of position data, positions identified as per spread selection - Card meaning as picked in field selection 1.4.5 Interfacing/Sourcing Details 1.4.5 Rules and Conditions - Data needs to be calculated for all fields, but only a maximum of 3 cards data should be shown in the free report. For the rest, a payment would be required. - Payment reports not in phase 1 - The report needs to be emailable (so functionality to convert to text file / html document should exist, which will then be emailed to the user’s email address).
