To test the module that loads data from a text file into the SQL Server database, follow these steps:

1. **Prepare Test Data**: Create a variety of text files with different data scenarios, including valid, invalid, and edge cases.

2. **Set Up Database**: Ensure the database is in a known state before the test (e.g., empty or with specific pre-loaded data).

3. **Execute the Load Process**: Run the module to load the data from the text file into the database.

4. **Verify Data Integrity**:
- Check that the correct number of records were inserted into each of the 10 tables.
- Validate that the data in the tables matches the data in the text file, including data types and formats.

5. **Check Referential Integrity**: Ensure that any foreign key relationships are maintained correctly across the tables.

6. **Test Error Handling**: Use invalid data to verify that the module handles errors gracefully and logs them appropriately.

Monday.Richard is a strange liar. He lies on six days of the week, but on the seventh day he always tells the truth. He made the following statements on three successive days: Day 1: "I lie on Monday and Tuesday." Day 2: "Today, it's Thursday, Saturday, or Sunday." Day 3: "I lie on Wednesday and Friday." On which day does Richard tell the truth?

DK BOSS Jul 30, 2021

We know that Richard tells the truth on only a single day of the week. If the statement on day 1 is untrue, this means that he tells the truth on Monday or Tuesday. If the statement on day 3 is untrue, this means that he tells the truth on Wednesday or Friday. Since Richard tells the truth on only one day, these statements cannot both be untrue. So, exactly one of these statements must be true, and the statement on day 2 must be untrue. Assume that the statement on day 1 is true. Then the statement on day 3 must be untrue, from which follows that Richard tells the truth on Wednesday or Friday. So, day 1 is a Wednesday or a Friday. Therefore, day 2 is a Thursday or a Saturday. However, this would imply that the statement on day 2 is true, which is impossible. From this we can conclude that the statement on day 1 must be untrue. This means that Richard told the truth on day 3 and that this day is a Monday or a Tuesday. So day 2 is a Sunday or a Monday. Because the statement on day 2 must be untrue, we can conclude that day 2 is a Monday. So day 3 is a Tuesday. Therefore, the day on which Richard tells the truth is Tuesday. .

Blackbox testing Software Testing Engineer/ Test Automation Engineer

Ques:- When would you choose bottom up methodology?

Asked In :- VECV, Kochar Infotech, vas, testhouse, textnow,

Right Answer:
You would choose the bottom-up methodology when you want to test individual components or modules first before integrating them into the overall system, especially when those components are well-defined and can be tested independently. This approach is useful when the components are complex and need thorough validation before integration.

Ques:- What is difference between BVA and Equivalence Partitioning ?can u explain BVA for three digits?

Asked In :- Intelligraphics, BCOM Computer Centre, mindpearl, newscred, housecall pro, clarasys, forter, planit software testing,

Right Answer:
Boundary Value Analysis (BVA) and Equivalence Partitioning are both testing techniques used in black-box testing.

**Difference:**
- **Equivalence Partitioning** divides input data into valid and invalid partitions to reduce the number of test cases. It assumes that all values in a partition will behave similarly.
- **Boundary Value Analysis** focuses on testing at the boundaries of these partitions, as errors often occur at the edges.

**BVA for three digits (0-999):**
- Valid boundaries: 0, 999
- Invalid boundaries: -1, 1000

Test cases would include:
1. Lower boundary: 0
2. Just above lower boundary: 1
3. Just below upper boundary: 998
4. Upper boundary: 999
5. Just above upper boundary: 1000
6. Just below lower boundary: -1
